Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619594, here are decompositions:

37 + 31619557 = 31619594
67 + 31619527 = 31619594
73 + 31619521 = 31619594
283 + 31619311 = 31619594
313 + 31619281 = 31619594
337 + 31619257 = 31619594
577 + 31619017 = 31619594
613 + 31618981 = 31619594

Showing the first eight; more decompositions exist.
