Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533540, here are decompositions:
- 7 + 31533533 = 31533540
- 23 + 31533517 = 31533540
- 29 + 31533511 = 31533540
- 41 + 31533499 = 31533540
- 43 + 31533497 = 31533540
- 79 + 31533461 = 31533540
- 89 + 31533451 = 31533540
- 109 + 31533431 = 31533540
Showing the first eight; more decompositions exist.
