Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489662, here are decompositions:

11 + 31489651 = 31489662
173 + 31489489 = 31489662
199 + 31489463 = 31489662
229 + 31489433 = 31489662
251 + 31489411 = 31489662
263 + 31489399 = 31489662
271 + 31489391 = 31489662
313 + 31489349 = 31489662

Showing the first eight; more decompositions exist.
