Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544086, here are decompositions:
- 29 + 31544057 = 31544086
- 47 + 31544039 = 31544086
- 53 + 31544033 = 31544086
- 89 + 31543997 = 31544086
- 107 + 31543979 = 31544086
- 173 + 31543913 = 31544086
- 179 + 31543907 = 31544086
- 227 + 31543859 = 31544086
Showing the first eight; more decompositions exist.
