Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537124, here are decompositions:

37 + 31537087 = 31537124
97 + 31537027 = 31537124
181 + 31536943 = 31537124
277 + 31536847 = 31537124
331 + 31536793 = 31537124
643 + 31536481 = 31537124
727 + 31536397 = 31537124
733 + 31536391 = 31537124

Showing the first eight; more decompositions exist.
