Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608360, here are decompositions:
- 11 + 31608349 = 31608360
- 19 + 31608341 = 31608360
- 23 + 31608337 = 31608360
- 41 + 31608319 = 31608360
- 59 + 31608301 = 31608360
- 89 + 31608271 = 31608360
- 97 + 31608263 = 31608360
- 191 + 31608169 = 31608360
Showing the first eight; more decompositions exist.
