Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550084, here are decompositions:
- 37 + 31550047 = 31550084
- 103 + 31549981 = 31550084
- 151 + 31549933 = 31550084
- 193 + 31549891 = 31550084
- 211 + 31549873 = 31550084
- 283 + 31549801 = 31550084
- 331 + 31549753 = 31550084
- 367 + 31549717 = 31550084
Showing the first eight; more decompositions exist.
