Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467752, here are decompositions:

31 + 31467721 = 31467752
61 + 31467691 = 31467752
163 + 31467589 = 31467752
181 + 31467571 = 31467752
193 + 31467559 = 31467752
271 + 31467481 = 31467752
523 + 31467229 = 31467752
571 + 31467181 = 31467752

Showing the first eight; more decompositions exist.
