Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477244, here are decompositions:

31 + 31477213 = 31477244
37 + 31477207 = 31477244
103 + 31477141 = 31477244
181 + 31477063 = 31477244
193 + 31477051 = 31477244
223 + 31477021 = 31477244
313 + 31476931 = 31477244
373 + 31476871 = 31477244

Showing the first eight; more decompositions exist.
