Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544856, here are decompositions:
- 29 + 31544827 = 31544856
- 37 + 31544819 = 31544856
- 73 + 31544783 = 31544856
- 97 + 31544759 = 31544856
- 107 + 31544749 = 31544856
- 137 + 31544719 = 31544856
- 139 + 31544717 = 31544856
- 199 + 31544657 = 31544856
Showing the first eight; more decompositions exist.
