Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12516, here are decompositions:
- 5 + 12511 = 12516
- 13 + 12503 = 12516
- 19 + 12497 = 12516
- 29 + 12487 = 12516
- 37 + 12479 = 12516
- 43 + 12473 = 12516
- 59 + 12457 = 12516
- 79 + 12437 = 12516
Showing the first eight; more decompositions exist.
