Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467782, here are decompositions:

19 + 31467763 = 31467782
61 + 31467721 = 31467782
193 + 31467589 = 31467782
211 + 31467571 = 31467782
223 + 31467559 = 31467782
349 + 31467433 = 31467782
523 + 31467259 = 31467782
601 + 31467181 = 31467782

Showing the first eight; more decompositions exist.
