Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549092, here are decompositions:

5 + 31549087 = 31549092
11 + 31549081 = 31549092
41 + 31549051 = 31549092
53 + 31549039 = 31549092
73 + 31549019 = 31549092
83 + 31549009 = 31549092
109 + 31548983 = 31549092
131 + 31548961 = 31549092

Showing the first eight; more decompositions exist.
