Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544032, here are decompositions:
- 11 + 31544021 = 31544032
- 41 + 31543991 = 31544032
- 53 + 31543979 = 31544032
- 71 + 31543961 = 31544032
- 173 + 31543859 = 31544032
- 263 + 31543769 = 31544032
- 269 + 31543763 = 31544032
- 281 + 31543751 = 31544032
Showing the first eight; more decompositions exist.
