Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61512, here are decompositions:
- 5 + 61507 = 61512
- 19 + 61493 = 61512
- 29 + 61483 = 61512
- 41 + 61471 = 61512
- 43 + 61469 = 61512
- 71 + 61441 = 61512
- 103 + 61409 = 61512
- 109 + 61403 = 61512
Showing the first eight; more decompositions exist.
