Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45528, here are decompositions:
- 5 + 45523 = 45528
- 31 + 45497 = 45528
- 37 + 45491 = 45528
- 47 + 45481 = 45528
- 89 + 45439 = 45528
- 101 + 45427 = 45528
- 139 + 45389 = 45528
- 151 + 45377 = 45528
Showing the first eight; more decompositions exist.
