Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559424, here are decompositions:
- 7 + 31559417 = 31559424
- 11 + 31559413 = 31559424
- 23 + 31559401 = 31559424
- 41 + 31559383 = 31559424
- 53 + 31559371 = 31559424
- 73 + 31559351 = 31559424
- 103 + 31559321 = 31559424
- 107 + 31559317 = 31559424
Showing the first eight; more decompositions exist.
