Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537202, here are decompositions:

163 + 31537039 = 31537202
199 + 31537003 = 31537202
211 + 31536991 = 31537202
331 + 31536871 = 31537202
373 + 31536829 = 31537202
379 + 31536823 = 31537202
409 + 31536793 = 31537202
673 + 31536529 = 31537202

Showing the first eight; more decompositions exist.
