Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55800, here are decompositions:
- 7 + 55793 = 55800
- 13 + 55787 = 55800
- 37 + 55763 = 55800
- 67 + 55733 = 55800
- 79 + 55721 = 55800
- 83 + 55717 = 55800
- 89 + 55711 = 55800
- 103 + 55697 = 55800
Showing the first eight; more decompositions exist.
