Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537148, here are decompositions:

61 + 31537087 = 31537148
109 + 31537039 = 31537148
157 + 31536991 = 31537148
211 + 31536937 = 31537148
277 + 31536871 = 31537148
541 + 31536607 = 31537148
619 + 31536529 = 31537148
751 + 31536397 = 31537148

Showing the first eight; more decompositions exist.
