Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489416, here are decompositions:

5 + 31489411 = 31489416
17 + 31489399 = 31489416
53 + 31489363 = 31489416
67 + 31489349 = 31489416
137 + 31489279 = 31489416
157 + 31489259 = 31489416
173 + 31489243 = 31489416
199 + 31489217 = 31489416

Showing the first eight; more decompositions exist.
