Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557566, here are decompositions:
- 3 + 31557563 = 31557566
- 13 + 31557553 = 31557566
- 37 + 31557529 = 31557566
- 43 + 31557523 = 31557566
- 199 + 31557367 = 31557566
- 223 + 31557343 = 31557566
- 283 + 31557283 = 31557566
- 349 + 31557217 = 31557566
Showing the first eight; more decompositions exist.
