Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465508, here are decompositions:

199 + 31465309 = 31465508
331 + 31465177 = 31465508
379 + 31465129 = 31465508
397 + 31465111 = 31465508
409 + 31465099 = 31465508
439 + 31465069 = 31465508
541 + 31464967 = 31465508
727 + 31464781 = 31465508

Showing the first eight; more decompositions exist.
