Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467738, here are decompositions:

11 + 31467727 = 31467738
17 + 31467721 = 31467738
19 + 31467719 = 31467738
47 + 31467691 = 31467738
61 + 31467677 = 31467738
149 + 31467589 = 31467738
151 + 31467587 = 31467738
167 + 31467571 = 31467738

Showing the first eight; more decompositions exist.
