Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537056, here are decompositions:

7 + 31537049 = 31537056
13 + 31537043 = 31537056
17 + 31537039 = 31537056
29 + 31537027 = 31537056
53 + 31537003 = 31537056
73 + 31536983 = 31537056
97 + 31536959 = 31537056
113 + 31536943 = 31537056

Showing the first eight; more decompositions exist.
