Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495426, here are decompositions:
- 3 + 31495423 = 31495426
- 23 + 31495403 = 31495426
- 59 + 31495367 = 31495426
- 227 + 31495199 = 31495426
- 239 + 31495187 = 31495426
- 269 + 31495157 = 31495426
- 317 + 31495109 = 31495426
- 383 + 31495043 = 31495426
Showing the first eight; more decompositions exist.
