Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537196, here are decompositions:

43 + 31537153 = 31537196
109 + 31537087 = 31537196
157 + 31537039 = 31537196
193 + 31537003 = 31537196
349 + 31536847 = 31537196
367 + 31536829 = 31537196
373 + 31536823 = 31537196
463 + 31536733 = 31537196

Showing the first eight; more decompositions exist.
