Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477148, here are decompositions:

7 + 31477141 = 31477148
37 + 31477111 = 31477148
97 + 31477051 = 31477148
127 + 31477021 = 31477148
277 + 31476871 = 31477148
349 + 31476799 = 31477148
421 + 31476727 = 31477148
457 + 31476691 = 31477148

Showing the first eight; more decompositions exist.
