Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544820, here are decompositions:
- 37 + 31544783 = 31544820
- 61 + 31544759 = 31544820
- 71 + 31544749 = 31544820
- 101 + 31544719 = 31544820
- 103 + 31544717 = 31544820
- 107 + 31544713 = 31544820
- 163 + 31544657 = 31544820
- 233 + 31544587 = 31544820
Showing the first eight; more decompositions exist.
