Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550074, here are decompositions:

11 + 31550063 = 31550074
47 + 31550027 = 31550074
53 + 31550021 = 31550074
107 + 31549967 = 31550074
293 + 31549781 = 31550074
383 + 31549691 = 31550074
467 + 31549607 = 31550074
683 + 31549391 = 31550074

Showing the first eight; more decompositions exist.
