Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572240, here are decompositions:
- 7 + 572233 = 572240
- 61 + 572179 = 572240
- 79 + 572161 = 572240
- 103 + 572137 = 572240
- 181 + 572059 = 572240
- 199 + 572041 = 572240
- 271 + 571969 = 572240
- 307 + 571933 = 572240
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 572,240 and was likely granted around 1896.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
