Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45680, here are decompositions:
- 3 + 45677 = 45680
- 7 + 45673 = 45680
- 13 + 45667 = 45680
- 67 + 45613 = 45680
- 127 + 45553 = 45680
- 139 + 45541 = 45680
- 157 + 45523 = 45680
- 199 + 45481 = 45680
Showing the first eight; more decompositions exist.
