Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12510, here are decompositions:
- 7 + 12503 = 12510
- 13 + 12497 = 12510
- 19 + 12491 = 12510
- 23 + 12487 = 12510
- 31 + 12479 = 12510
- 37 + 12473 = 12510
- 53 + 12457 = 12510
- 59 + 12451 = 12510
Showing the first eight; more decompositions exist.
