Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61510, here are decompositions:
- 3 + 61507 = 61510
- 17 + 61493 = 61510
- 23 + 61487 = 61510
- 41 + 61469 = 61510
- 47 + 61463 = 61510
- 101 + 61409 = 61510
- 107 + 61403 = 61510
- 131 + 61379 = 61510
Showing the first eight; more decompositions exist.
