Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477792, here are decompositions:

11 + 31477781 = 31477792
41 + 31477751 = 31477792
239 + 31477553 = 31477792
443 + 31477349 = 31477792
491 + 31477301 = 31477792
503 + 31477289 = 31477792
911 + 31476881 = 31477792
971 + 31476821 = 31477792

Showing the first eight; more decompositions exist.
