Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511594, here are decompositions:

43 + 31511551 = 31511594
61 + 31511533 = 31511594
67 + 31511527 = 31511594
157 + 31511437 = 31511594
307 + 31511287 = 31511594
313 + 31511281 = 31511594
523 + 31511071 = 31511594
601 + 31510993 = 31511594

Showing the first eight; more decompositions exist.
