Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 958720, here are decompositions:
- 41 + 958679 = 958720
- 47 + 958673 = 958720
- 53 + 958667 = 958720
- 83 + 958637 = 958720
- 167 + 958553 = 958720
- 173 + 958547 = 958720
- 179 + 958541 = 958720
- 197 + 958523 = 958720
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 958,720 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 958720 first appears in π at position 811,527 of the decimal expansion (the 811,527ordinal-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.
