Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477104, here are decompositions:

5 + 31477099 = 31477104
37 + 31477067 = 31477104
41 + 31477063 = 31477104
47 + 31477057 = 31477104
53 + 31477051 = 31477104
83 + 31477021 = 31477104
157 + 31476947 = 31477104
173 + 31476931 = 31477104

Showing the first eight; more decompositions exist.
