Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549526, here are decompositions:

199 + 31549327 = 31549526
409 + 31549117 = 31549526
439 + 31549087 = 31549526
487 + 31549039 = 31549526
709 + 31548817 = 31549526
769 + 31548757 = 31549526
787 + 31548739 = 31549526
829 + 31548697 = 31549526

Showing the first eight; more decompositions exist.
