Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463698, here are decompositions:

17 + 31463681 = 31463698
107 + 31463591 = 31463698
179 + 31463519 = 31463698
191 + 31463507 = 31463698
239 + 31463459 = 31463698
269 + 31463429 = 31463698
311 + 31463387 = 31463698
449 + 31463249 = 31463698

Showing the first eight; more decompositions exist.
