Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467898, here are decompositions:

5 + 31467893 = 31467898
89 + 31467809 = 31467898
131 + 31467767 = 31467898
179 + 31467719 = 31467898
251 + 31467647 = 31467898
311 + 31467587 = 31467898
347 + 31467551 = 31467898
359 + 31467539 = 31467898

Showing the first eight; more decompositions exist.
