Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489826, here are decompositions:

7 + 31489819 = 31489826
73 + 31489753 = 31489826
79 + 31489747 = 31489826
103 + 31489723 = 31489826
163 + 31489663 = 31489826
307 + 31489519 = 31489826
337 + 31489489 = 31489826
409 + 31489417 = 31489826

Showing the first eight; more decompositions exist.
