Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602120, here are decompositions:
- 23 + 31602097 = 31602120
- 41 + 31602079 = 31602120
- 71 + 31602049 = 31602120
- 79 + 31602041 = 31602120
- 103 + 31602017 = 31602120
- 197 + 31601923 = 31602120
- 223 + 31601897 = 31602120
- 229 + 31601891 = 31602120
Showing the first eight; more decompositions exist.
