Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486126, here are decompositions:
- 3 + 31486123 = 31486126
- 5 + 31486121 = 31486126
- 17 + 31486109 = 31486126
- 167 + 31485959 = 31486126
- 173 + 31485953 = 31486126
- 233 + 31485893 = 31486126
- 293 + 31485833 = 31486126
- 359 + 31485767 = 31486126
Showing the first eight; more decompositions exist.
