Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489934, here are decompositions:

61 + 31489873 = 31489934
181 + 31489753 = 31489934
211 + 31489723 = 31489934
271 + 31489663 = 31489934
283 + 31489651 = 31489934
523 + 31489411 = 31489934
571 + 31489363 = 31489934
691 + 31489243 = 31489934

Showing the first eight; more decompositions exist.
