Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467750, here are decompositions:

23 + 31467727 = 31467750
29 + 31467721 = 31467750
31 + 31467719 = 31467750
59 + 31467691 = 31467750
73 + 31467677 = 31467750
103 + 31467647 = 31467750
157 + 31467593 = 31467750
163 + 31467587 = 31467750

Showing the first eight; more decompositions exist.
