Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61524, here are decompositions:
- 5 + 61519 = 61524
- 13 + 61511 = 61524
- 17 + 61507 = 61524
- 31 + 61493 = 61524
- 37 + 61487 = 61524
- 41 + 61483 = 61524
- 53 + 61471 = 61524
- 61 + 61463 = 61524
Showing the first eight; more decompositions exist.
