Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66480, here are decompositions:
- 13 + 66467 = 66480
- 17 + 66463 = 66480
- 23 + 66457 = 66480
- 31 + 66449 = 66480
- 67 + 66413 = 66480
- 97 + 66383 = 66480
- 103 + 66377 = 66480
- 107 + 66373 = 66480
Showing the first eight; more decompositions exist.
