Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519750, here are decompositions:
- 47 + 31519703 = 31519750
- 71 + 31519679 = 31519750
- 89 + 31519661 = 31519750
- 149 + 31519601 = 31519750
- 167 + 31519583 = 31519750
- 179 + 31519571 = 31519750
- 263 + 31519487 = 31519750
- 293 + 31519457 = 31519750
Showing the first eight; more decompositions exist.
