Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601168, here are decompositions:
- 31 + 31601137 = 31601168
- 127 + 31601041 = 31601168
- 199 + 31600969 = 31601168
- 211 + 31600957 = 31601168
- 307 + 31600861 = 31601168
- 367 + 31600801 = 31601168
- 397 + 31600771 = 31601168
- 499 + 31600669 = 31601168
Showing the first eight; more decompositions exist.
