Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544042, here are decompositions:
- 3 + 31544039 = 31544042
- 31 + 31544011 = 31544042
- 139 + 31543903 = 31544042
- 199 + 31543843 = 31544042
- 331 + 31543711 = 31544042
- 373 + 31543669 = 31544042
- 463 + 31543579 = 31544042
- 499 + 31543543 = 31544042
Showing the first eight; more decompositions exist.
