Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518604, here are decompositions:
- 3 + 31518601 = 31518604
- 11 + 31518593 = 31518604
- 83 + 31518521 = 31518604
- 113 + 31518491 = 31518604
- 137 + 31518467 = 31518604
- 251 + 31518353 = 31518604
- 317 + 31518287 = 31518604
- 431 + 31518173 = 31518604
Showing the first eight; more decompositions exist.
