Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567982, here are decompositions:

163 + 31567819 = 31567982
241 + 31567741 = 31567982
283 + 31567699 = 31567982
379 + 31567603 = 31567982
571 + 31567411 = 31567982
613 + 31567369 = 31567982
751 + 31567231 = 31567982
769 + 31567213 = 31567982

Showing the first eight; more decompositions exist.
