Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534620, here are decompositions:
- 23 + 31534597 = 31534620
- 31 + 31534589 = 31534620
- 59 + 31534561 = 31534620
- 67 + 31534553 = 31534620
- 127 + 31534493 = 31534620
- 137 + 31534483 = 31534620
- 163 + 31534457 = 31534620
- 179 + 31534441 = 31534620
Showing the first eight; more decompositions exist.
