Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477118, here are decompositions:

7 + 31477111 = 31477118
19 + 31477099 = 31477118
61 + 31477057 = 31477118
67 + 31477051 = 31477118
97 + 31477021 = 31477118
271 + 31476847 = 31477118
487 + 31476631 = 31477118
571 + 31476547 = 31477118

Showing the first eight; more decompositions exist.
