Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533558, here are decompositions:
- 11 + 31533547 = 31533558
- 41 + 31533517 = 31533558
- 47 + 31533511 = 31533558
- 59 + 31533499 = 31533558
- 61 + 31533497 = 31533558
- 97 + 31533461 = 31533558
- 107 + 31533451 = 31533558
- 109 + 31533449 = 31533558
Showing the first eight; more decompositions exist.
