Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537244, here are decompositions:

43 + 31537201 = 31537244
97 + 31537147 = 31537244
157 + 31537087 = 31537244
241 + 31537003 = 31537244
307 + 31536937 = 31537244
373 + 31536871 = 31537244
397 + 31536847 = 31537244
421 + 31536823 = 31537244

Showing the first eight; more decompositions exist.
