Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544038, here are decompositions:
- 5 + 31544033 = 31544038
- 17 + 31544021 = 31544038
- 41 + 31543997 = 31544038
- 47 + 31543991 = 31544038
- 59 + 31543979 = 31544038
- 131 + 31543907 = 31544038
- 167 + 31543871 = 31544038
- 179 + 31543859 = 31544038
Showing the first eight; more decompositions exist.
