Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544088, here are decompositions:
- 11 + 31544077 = 31544088
- 31 + 31544057 = 31544088
- 47 + 31544041 = 31544088
- 67 + 31544021 = 31544088
- 97 + 31543991 = 31544088
- 101 + 31543987 = 31544088
- 109 + 31543979 = 31544088
- 127 + 31543961 = 31544088
Showing the first eight; more decompositions exist.
