Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489676, here are decompositions:

3 + 31489673 = 31489676
13 + 31489663 = 31489676
157 + 31489519 = 31489676
277 + 31489399 = 31489676
313 + 31489363 = 31489676
397 + 31489279 = 31489676
433 + 31489243 = 31489676
499 + 31489177 = 31489676

Showing the first eight; more decompositions exist.
