Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477202, here are decompositions:

61 + 31477141 = 31477202
103 + 31477099 = 31477202
139 + 31477063 = 31477202
151 + 31477051 = 31477202
181 + 31477021 = 31477202
271 + 31476931 = 31477202
331 + 31476871 = 31477202
349 + 31476853 = 31477202

Showing the first eight; more decompositions exist.
