Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467770, here are decompositions:

3 + 31467767 = 31467770
7 + 31467763 = 31467770
43 + 31467727 = 31467770
79 + 31467691 = 31467770
181 + 31467589 = 31467770
199 + 31467571 = 31467770
211 + 31467559 = 31467770
337 + 31467433 = 31467770

Showing the first eight; more decompositions exist.
