Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12490, here are decompositions:
- 3 + 12487 = 12490
- 11 + 12479 = 12490
- 17 + 12473 = 12490
- 53 + 12437 = 12490
- 89 + 12401 = 12490
- 113 + 12377 = 12490
- 167 + 12323 = 12490
- 227 + 12263 = 12490
Showing the first eight; more decompositions exist.
