Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544862, here are decompositions:
- 5 + 31544857 = 31544862
- 43 + 31544819 = 31544862
- 79 + 31544783 = 31544862
- 103 + 31544759 = 31544862
- 113 + 31544749 = 31544862
- 149 + 31544713 = 31544862
- 311 + 31544551 = 31544862
- 331 + 31544531 = 31544862
Showing the first eight; more decompositions exist.
