Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616242, here are decompositions:
- 11 + 31616231 = 31616242
- 23 + 31616219 = 31616242
- 59 + 31616183 = 31616242
- 113 + 31616129 = 31616242
- 173 + 31616069 = 31616242
- 233 + 31616009 = 31616242
- 263 + 31615979 = 31616242
- 269 + 31615973 = 31616242
Showing the first eight; more decompositions exist.
