Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530456, here are decompositions:
- 5 + 31530451 = 31530456
- 19 + 31530437 = 31530456
- 37 + 31530419 = 31530456
- 47 + 31530409 = 31530456
- 73 + 31530383 = 31530456
- 79 + 31530377 = 31530456
- 107 + 31530349 = 31530456
- 109 + 31530347 = 31530456
Showing the first eight; more decompositions exist.
