Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537046, here are decompositions:

3 + 31537043 = 31537046
7 + 31537039 = 31537046
19 + 31537027 = 31537046
43 + 31537003 = 31537046
103 + 31536943 = 31537046
109 + 31536937 = 31537046
199 + 31536847 = 31537046
223 + 31536823 = 31537046

Showing the first eight; more decompositions exist.
