Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006720, here are decompositions:
- 83 + 1006637 = 1006720
- 107 + 1006613 = 1006720
- 131 + 1006589 = 1006720
- 137 + 1006583 = 1006720
- 173 + 1006547 = 1006720
- 227 + 1006493 = 1006720
- 251 + 1006469 = 1006720
- 257 + 1006463 = 1006720
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,006,720 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 1006720 first appears in π at position 543,520 of the decimal expansion (the 543,520ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
