Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560086, here are decompositions:

7 + 31560079 = 31560086
13 + 31560073 = 31560086
67 + 31560019 = 31560086
97 + 31559989 = 31560086
109 + 31559977 = 31560086
277 + 31559809 = 31560086
367 + 31559719 = 31560086
409 + 31559677 = 31560086

Showing the first eight; more decompositions exist.
