Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489698, here are decompositions:

47 + 31489651 = 31489698
127 + 31489571 = 31489698
157 + 31489541 = 31489698
179 + 31489519 = 31489698
271 + 31489427 = 31489698
281 + 31489417 = 31489698
307 + 31489391 = 31489698
349 + 31489349 = 31489698

Showing the first eight; more decompositions exist.
