Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544928, here are decompositions:
- 5 + 31544923 = 31544928
- 29 + 31544899 = 31544928
- 71 + 31544857 = 31544928
- 101 + 31544827 = 31544928
- 109 + 31544819 = 31544928
- 157 + 31544771 = 31544928
- 179 + 31544749 = 31544928
- 211 + 31544717 = 31544928
Showing the first eight; more decompositions exist.
