Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544902, here are decompositions:
- 3 + 31544899 = 31544902
- 23 + 31544879 = 31544902
- 83 + 31544819 = 31544902
- 131 + 31544771 = 31544902
- 359 + 31544543 = 31544902
- 509 + 31544393 = 31544902
- 863 + 31544039 = 31544902
- 881 + 31544021 = 31544902
Showing the first eight; more decompositions exist.
