Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534632, here are decompositions:
- 43 + 31534589 = 31534632
- 71 + 31534561 = 31534632
- 79 + 31534553 = 31534632
- 89 + 31534543 = 31534632
- 131 + 31534501 = 31534632
- 139 + 31534493 = 31534632
- 149 + 31534483 = 31534632
- 191 + 31534441 = 31534632
Showing the first eight; more decompositions exist.
