Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544850, here are decompositions:
- 23 + 31544827 = 31544850
- 31 + 31544819 = 31544850
- 67 + 31544783 = 31544850
- 79 + 31544771 = 31544850
- 101 + 31544749 = 31544850
- 131 + 31544719 = 31544850
- 137 + 31544713 = 31544850
- 193 + 31544657 = 31544850
Showing the first eight; more decompositions exist.
