Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509712, here are decompositions:
- 13 + 509699 = 509712
- 19 + 509693 = 509712
- 23 + 509689 = 509712
- 31 + 509681 = 509712
- 53 + 509659 = 509712
- 59 + 509653 = 509712
- 79 + 509633 = 509712
- 89 + 509623 = 509712
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 509,712 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 509712 first appears in π at position 957,245 of the decimal expansion (the 957,245ordinal-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.
