Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534086, here are decompositions:

7 + 31534079 = 31534086
13 + 31534073 = 31534086
19 + 31534067 = 31534086
29 + 31534057 = 31534086
53 + 31534033 = 31534086
107 + 31533979 = 31534086
127 + 31533959 = 31534086
137 + 31533949 = 31534086

Showing the first eight; more decompositions exist.
