Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489586, here are decompositions:

67 + 31489519 = 31489586
97 + 31489489 = 31489586
223 + 31489363 = 31489586
307 + 31489279 = 31489586
409 + 31489177 = 31489586
439 + 31489147 = 31489586
523 + 31489063 = 31489586
577 + 31489009 = 31489586

Showing the first eight; more decompositions exist.
