Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55728, here are decompositions:
- 7 + 55721 = 55728
- 11 + 55717 = 55728
- 17 + 55711 = 55728
- 31 + 55697 = 55728
- 37 + 55691 = 55728
- 47 + 55681 = 55728
- 61 + 55667 = 55728
- 67 + 55661 = 55728
Showing the first eight; more decompositions exist.
