Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489562, here are decompositions:

43 + 31489519 = 31489562
73 + 31489489 = 31489562
151 + 31489411 = 31489562
163 + 31489399 = 31489562
199 + 31489363 = 31489562
283 + 31489279 = 31489562
499 + 31489063 = 31489562
571 + 31488991 = 31489562

Showing the first eight; more decompositions exist.
