Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550044, here are decompositions:

17 + 31550027 = 31550044
23 + 31550021 = 31550044
263 + 31549781 = 31550044
293 + 31549751 = 31550044
311 + 31549733 = 31550044
353 + 31549691 = 31550044
593 + 31549451 = 31550044
641 + 31549403 = 31550044

Showing the first eight; more decompositions exist.
