Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530546, here are decompositions:
- 23 + 31530523 = 31530546
- 59 + 31530487 = 31530546
- 67 + 31530479 = 31530546
- 109 + 31530437 = 31530546
- 127 + 31530419 = 31530546
- 137 + 31530409 = 31530546
- 163 + 31530383 = 31530546
- 197 + 31530349 = 31530546
Showing the first eight; more decompositions exist.
