Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449426, here are decompositions:
- 5 + 31449421 = 31449426
- 17 + 31449409 = 31449426
- 23 + 31449403 = 31449426
- 53 + 31449373 = 31449426
- 67 + 31449359 = 31449426
- 103 + 31449323 = 31449426
- 137 + 31449289 = 31449426
- 139 + 31449287 = 31449426
Showing the first eight; more decompositions exist.
