Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467698, here are decompositions:

7 + 31467691 = 31467698
109 + 31467589 = 31467698
127 + 31467571 = 31467698
139 + 31467559 = 31467698
331 + 31467367 = 31467698
397 + 31467301 = 31467698
439 + 31467259 = 31467698
499 + 31467199 = 31467698

Showing the first eight; more decompositions exist.
