Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544046, here are decompositions:
- 5 + 31544041 = 31544046
- 7 + 31544039 = 31544046
- 13 + 31544033 = 31544046
- 59 + 31543987 = 31544046
- 67 + 31543979 = 31544046
- 139 + 31543907 = 31544046
- 173 + 31543873 = 31544046
- 199 + 31543847 = 31544046
Showing the first eight; more decompositions exist.
