Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55806, here are decompositions:
- 7 + 55799 = 55806
- 13 + 55793 = 55806
- 19 + 55787 = 55806
- 43 + 55763 = 55806
- 73 + 55733 = 55806
- 89 + 55717 = 55806
- 109 + 55697 = 55806
- 139 + 55667 = 55806
Showing the first eight; more decompositions exist.
