Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486042, here are decompositions:
- 83 + 31485959 = 31486042
- 89 + 31485953 = 31486042
- 101 + 31485941 = 31486042
- 149 + 31485893 = 31486042
- 239 + 31485803 = 31486042
- 251 + 31485791 = 31486042
- 293 + 31485749 = 31486042
- 389 + 31485653 = 31486042
Showing the first eight; more decompositions exist.
