Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467908, here are decompositions:

61 + 31467847 = 31467908
79 + 31467829 = 31467908
97 + 31467811 = 31467908
181 + 31467727 = 31467908
337 + 31467571 = 31467908
349 + 31467559 = 31467908
541 + 31467367 = 31467908
607 + 31467301 = 31467908

Showing the first eight; more decompositions exist.
