Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7492, here are decompositions:
- 3 + 7489 = 7492
- 5 + 7487 = 7492
- 11 + 7481 = 7492
- 41 + 7451 = 7492
- 59 + 7433 = 7492
- 239 + 7253 = 7492
- 263 + 7229 = 7492
- 281 + 7211 = 7492
Showing the first eight; more decompositions exist.
