Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506616, here are decompositions:
- 17 + 31506599 = 31506616
- 47 + 31506569 = 31506616
- 137 + 31506479 = 31506616
- 173 + 31506443 = 31506616
- 179 + 31506437 = 31506616
- 257 + 31506359 = 31506616
- 263 + 31506353 = 31506616
- 353 + 31506263 = 31506616
Showing the first eight; more decompositions exist.
