Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544880, here are decompositions:
- 23 + 31544857 = 31544880
- 53 + 31544827 = 31544880
- 61 + 31544819 = 31544880
- 97 + 31544783 = 31544880
- 109 + 31544771 = 31544880
- 131 + 31544749 = 31544880
- 163 + 31544717 = 31544880
- 167 + 31544713 = 31544880
Showing the first eight; more decompositions exist.
