Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530420, here are decompositions:
- 11 + 31530409 = 31530420
- 29 + 31530391 = 31530420
- 37 + 31530383 = 31530420
- 43 + 31530377 = 31530420
- 71 + 31530349 = 31530420
- 73 + 31530347 = 31530420
- 79 + 31530341 = 31530420
- 109 + 31530311 = 31530420
Showing the first eight; more decompositions exist.
