Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31426, here are decompositions:
- 29 + 31397 = 31426
- 47 + 31379 = 31426
- 89 + 31337 = 31426
- 107 + 31319 = 31426
- 149 + 31277 = 31426
- 167 + 31259 = 31426
- 173 + 31253 = 31426
- 179 + 31247 = 31426
Showing the first eight; more decompositions exist.
