Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449674, here are decompositions:
- 37 + 31449637 = 31449674
- 97 + 31449577 = 31449674
- 103 + 31449571 = 31449674
- 181 + 31449493 = 31449674
- 211 + 31449463 = 31449674
- 271 + 31449403 = 31449674
- 313 + 31449361 = 31449674
- 433 + 31449241 = 31449674
Showing the first eight; more decompositions exist.
