Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544556, here are decompositions:
- 5 + 31544551 = 31544556
- 13 + 31544543 = 31544556
- 23 + 31544533 = 31544556
- 47 + 31544509 = 31544556
- 139 + 31544417 = 31544556
- 163 + 31544393 = 31544556
- 193 + 31544363 = 31544556
- 233 + 31544323 = 31544556
Showing the first eight; more decompositions exist.
