Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619562, here are decompositions:

5 + 31619557 = 31619562
19 + 31619543 = 31619562
31 + 31619531 = 31619562
41 + 31619521 = 31619562
43 + 31619519 = 31619562
53 + 31619509 = 31619562
61 + 31619501 = 31619562
103 + 31619459 = 31619562

Showing the first eight; more decompositions exist.
