Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533480, here are decompositions:
- 19 + 31533461 = 31533480
- 29 + 31533451 = 31533480
- 31 + 31533449 = 31533480
- 67 + 31533413 = 31533480
- 71 + 31533409 = 31533480
- 101 + 31533379 = 31533480
- 109 + 31533371 = 31533480
- 137 + 31533343 = 31533480
Showing the first eight; more decompositions exist.
