Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602636, here are decompositions:
- 5 + 31602631 = 31602636
- 47 + 31602589 = 31602636
- 97 + 31602539 = 31602636
- 139 + 31602497 = 31602636
- 179 + 31602457 = 31602636
- 193 + 31602443 = 31602636
- 239 + 31602397 = 31602636
- 269 + 31602367 = 31602636
Showing the first eight; more decompositions exist.
