Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487594, here are decompositions:

13 + 31487581 = 31487594
43 + 31487551 = 31487594
67 + 31487527 = 31487594
277 + 31487317 = 31487594
283 + 31487311 = 31487594
331 + 31487263 = 31487594
613 + 31486981 = 31487594
883 + 31486711 = 31487594

Showing the first eight; more decompositions exist.
