Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537106, here are decompositions:

19 + 31537087 = 31537106
67 + 31537039 = 31537106
79 + 31537027 = 31537106
103 + 31537003 = 31537106
163 + 31536943 = 31537106
277 + 31536829 = 31537106
283 + 31536823 = 31537106
313 + 31536793 = 31537106

Showing the first eight; more decompositions exist.
