Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477002, here are decompositions:

43 + 31476959 = 31477002
71 + 31476931 = 31477002
131 + 31476871 = 31477002
149 + 31476853 = 31477002
173 + 31476829 = 31477002
181 + 31476821 = 31477002
269 + 31476733 = 31477002
311 + 31476691 = 31477002

Showing the first eight; more decompositions exist.
