Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160740, here are decompositions:
- 17 + 160723 = 160740
- 29 + 160711 = 160740
- 31 + 160709 = 160740
- 43 + 160697 = 160740
- 53 + 160687 = 160740
- 59 + 160681 = 160740
- 71 + 160669 = 160740
- 89 + 160651 = 160740
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 160,740 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 160740 first appears in π at position 161,827 of the decimal expansion (the 161,827ordinal-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.
