Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156124, here are decompositions:
- 5 + 156119 = 156124
- 53 + 156071 = 156124
- 83 + 156041 = 156124
- 113 + 156011 = 156124
- 233 + 155891 = 156124
- 263 + 155861 = 156124
- 347 + 155777 = 156124
- 383 + 155741 = 156124
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 156,124 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
