Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45420, here are decompositions:
- 7 + 45413 = 45420
- 17 + 45403 = 45420
- 31 + 45389 = 45420
- 43 + 45377 = 45420
- 59 + 45361 = 45420
- 79 + 45341 = 45420
- 83 + 45337 = 45420
- 101 + 45319 = 45420
Showing the first eight; more decompositions exist.
