Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495216, here are decompositions:
- 3 + 31495213 = 31495216
- 17 + 31495199 = 31495216
- 29 + 31495187 = 31495216
- 59 + 31495157 = 31495216
- 107 + 31495109 = 31495216
- 173 + 31495043 = 31495216
- 197 + 31495019 = 31495216
- 293 + 31494923 = 31495216
Showing the first eight; more decompositions exist.
