Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477696, here are decompositions:

113 + 31477583 = 31477696
269 + 31477427 = 31477696
317 + 31477379 = 31477696
347 + 31477349 = 31477696
617 + 31477079 = 31477696
953 + 31476743 = 31477696
1103 + 31476593 = 31477696
1109 + 31476587 = 31477696

Showing the first eight; more decompositions exist.
