Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467578, here are decompositions:

7 + 31467571 = 31467578
19 + 31467559 = 31467578
97 + 31467481 = 31467578
211 + 31467367 = 31467578
277 + 31467301 = 31467578
349 + 31467229 = 31467578
379 + 31467199 = 31467578
397 + 31467181 = 31467578

Showing the first eight; more decompositions exist.
