Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608434, here are decompositions:
- 7 + 31608427 = 31608434
- 97 + 31608337 = 31608434
- 163 + 31608271 = 31608434
- 271 + 31608163 = 31608434
- 367 + 31608067 = 31608434
- 373 + 31608061 = 31608434
- 397 + 31608037 = 31608434
- 421 + 31608013 = 31608434
Showing the first eight; more decompositions exist.
