Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549432, here are decompositions:

29 + 31549403 = 31549432
41 + 31549391 = 31549432
59 + 31549373 = 31549432
191 + 31549241 = 31549432
251 + 31549181 = 31549432
389 + 31549043 = 31549432
449 + 31548983 = 31549432
479 + 31548953 = 31549432

Showing the first eight; more decompositions exist.
