Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15612, here are decompositions:
- 5 + 15607 = 15612
- 11 + 15601 = 15612
- 29 + 15583 = 15612
- 31 + 15581 = 15612
- 43 + 15569 = 15612
- 53 + 15559 = 15612
- 61 + 15551 = 15612
- 71 + 15541 = 15612
Showing the first eight; more decompositions exist.
