Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602064, here are decompositions:
- 23 + 31602041 = 31602064
- 47 + 31602017 = 31602064
- 167 + 31601897 = 31602064
- 173 + 31601891 = 31602064
- 191 + 31601873 = 31602064
- 227 + 31601837 = 31602064
- 281 + 31601783 = 31602064
- 353 + 31601711 = 31602064
Showing the first eight; more decompositions exist.
