Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543720, here are decompositions:
- 7 + 543713 = 543720
- 13 + 543707 = 543720
- 17 + 543703 = 543720
- 31 + 543689 = 543720
- 41 + 543679 = 543720
- 59 + 543661 = 543720
- 61 + 543659 = 543720
- 83 + 543637 = 543720
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 543,720 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
