Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572320, here are decompositions:
- 17 + 572303 = 572320
- 113 + 572207 = 572320
- 137 + 572183 = 572320
- 227 + 572093 = 572320
- 233 + 572087 = 572320
- 251 + 572069 = 572320
- 257 + 572063 = 572320
- 269 + 572051 = 572320
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 572,320 and was likely granted around 1896.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
