Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467630, here are decompositions:

37 + 31467593 = 31467630
41 + 31467589 = 31467630
43 + 31467587 = 31467630
59 + 31467571 = 31467630
71 + 31467559 = 31467630
79 + 31467551 = 31467630
97 + 31467533 = 31467630
127 + 31467503 = 31467630

Showing the first eight; more decompositions exist.
