Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63660, here are decompositions:
- 11 + 63649 = 63660
- 13 + 63647 = 63660
- 31 + 63629 = 63660
- 43 + 63617 = 63660
- 53 + 63607 = 63660
- 59 + 63601 = 63660
- 61 + 63599 = 63660
- 71 + 63589 = 63660
Showing the first eight; more decompositions exist.
