Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489682, here are decompositions:

19 + 31489663 = 31489682
31 + 31489651 = 31489682
163 + 31489519 = 31489682
193 + 31489489 = 31489682
271 + 31489411 = 31489682
283 + 31489399 = 31489682
439 + 31489243 = 31489682
613 + 31489069 = 31489682

Showing the first eight; more decompositions exist.
