Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467548, here are decompositions:

67 + 31467481 = 31467548
181 + 31467367 = 31467548
349 + 31467199 = 31467548
367 + 31467181 = 31467548
379 + 31467169 = 31467548
421 + 31467127 = 31467548
571 + 31466977 = 31467548
691 + 31466857 = 31467548

Showing the first eight; more decompositions exist.
