Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109572, here are decompositions:
- 5 + 109567 = 109572
- 31 + 109541 = 109572
- 53 + 109519 = 109572
- 101 + 109471 = 109572
- 103 + 109469 = 109572
- 131 + 109441 = 109572
- 139 + 109433 = 109572
- 149 + 109423 = 109572
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 109,572 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
