Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544908, here are decompositions:
- 29 + 31544879 = 31544908
- 89 + 31544819 = 31544908
- 137 + 31544771 = 31544908
- 149 + 31544759 = 31544908
- 191 + 31544717 = 31544908
- 251 + 31544657 = 31544908
- 347 + 31544561 = 31544908
- 491 + 31544417 = 31544908
Showing the first eight; more decompositions exist.
