Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611784, here are decompositions:
- 23 + 31611761 = 31611784
- 47 + 31611737 = 31611784
- 137 + 31611647 = 31611784
- 167 + 31611617 = 31611784
- 257 + 31611527 = 31611784
- 311 + 31611473 = 31611784
- 317 + 31611467 = 31611784
- 443 + 31611341 = 31611784
Showing the first eight; more decompositions exist.
