Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544194, here are decompositions:
- 5 + 31544189 = 31544194
- 23 + 31544171 = 31544194
- 41 + 31544153 = 31544194
- 137 + 31544057 = 31544194
- 173 + 31544021 = 31544194
- 197 + 31543997 = 31544194
- 233 + 31543961 = 31544194
- 281 + 31543913 = 31544194
Showing the first eight; more decompositions exist.
