Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467650, here are decompositions:

3 + 31467647 = 31467650
61 + 31467589 = 31467650
79 + 31467571 = 31467650
283 + 31467367 = 31467650
349 + 31467301 = 31467650
421 + 31467229 = 31467650
523 + 31467127 = 31467650
547 + 31467103 = 31467650

Showing the first eight; more decompositions exist.
