Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157370, here are decompositions:
- 7 + 157363 = 157370
- 19 + 157351 = 157370
- 43 + 157327 = 157370
- 67 + 157303 = 157370
- 79 + 157291 = 157370
- 97 + 157273 = 157370
- 127 + 157243 = 157370
- 139 + 157231 = 157370
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 157,370 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
