Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550086, here are decompositions:

23 + 31550063 = 31550086
59 + 31550027 = 31550086
107 + 31549979 = 31550086
167 + 31549919 = 31550086
257 + 31549829 = 31550086
353 + 31549733 = 31550086
419 + 31549667 = 31550086
479 + 31549607 = 31550086

Showing the first eight; more decompositions exist.
