Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530612, here are decompositions:
- 5 + 31530607 = 31530612
- 19 + 31530593 = 31530612
- 23 + 31530589 = 31530612
- 41 + 31530571 = 31530612
- 89 + 31530523 = 31530612
- 193 + 31530419 = 31530612
- 229 + 31530383 = 31530612
- 263 + 31530349 = 31530612
Showing the first eight; more decompositions exist.
