Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549088, here are decompositions:

7 + 31549081 = 31549088
37 + 31549051 = 31549088
79 + 31549009 = 31549088
127 + 31548961 = 31549088
271 + 31548817 = 31549088
331 + 31548757 = 31549088
349 + 31548739 = 31549088
541 + 31548547 = 31549088

Showing the first eight; more decompositions exist.
