Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533456, here are decompositions:
- 5 + 31533451 = 31533456
- 7 + 31533449 = 31533456
- 43 + 31533413 = 31533456
- 47 + 31533409 = 31533456
- 67 + 31533389 = 31533456
- 113 + 31533343 = 31533456
- 197 + 31533259 = 31533456
- 307 + 31533149 = 31533456
Showing the first eight; more decompositions exist.
