Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489410, here are decompositions:

11 + 31489399 = 31489410
19 + 31489391 = 31489410
47 + 31489363 = 31489410
61 + 31489349 = 31489410
131 + 31489279 = 31489410
151 + 31489259 = 31489410
163 + 31489247 = 31489410
167 + 31489243 = 31489410

Showing the first eight; more decompositions exist.
