Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 461720, here are decompositions:
- 3 + 461717 = 461720
- 13 + 461707 = 461720
- 31 + 461689 = 461720
- 43 + 461677 = 461720
- 67 + 461653 = 461720
- 139 + 461581 = 461720
- 151 + 461569 = 461720
- 199 + 461521 = 461720
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 461,720 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 461720 first appears in π at position 293,510 of the decimal expansion (the 293,510ordinal-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.
