Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611384, here are decompositions:
- 5 + 31611379 = 31611384
- 17 + 31611367 = 31611384
- 43 + 31611341 = 31611384
- 61 + 31611323 = 31611384
- 73 + 31611311 = 31611384
- 83 + 31611301 = 31611384
- 113 + 31611271 = 31611384
- 197 + 31611187 = 31611384
Showing the first eight; more decompositions exist.
