Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489524, here are decompositions:

5 + 31489519 = 31489524
61 + 31489463 = 31489524
97 + 31489427 = 31489524
107 + 31489417 = 31489524
113 + 31489411 = 31489524
277 + 31489247 = 31489524
281 + 31489243 = 31489524
307 + 31489217 = 31489524

Showing the first eight; more decompositions exist.
