Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537082, here are decompositions:

43 + 31537039 = 31537082
79 + 31537003 = 31537082
139 + 31536943 = 31537082
211 + 31536871 = 31537082
349 + 31536733 = 31537082
601 + 31536481 = 31537082
691 + 31536391 = 31537082
769 + 31536313 = 31537082

Showing the first eight; more decompositions exist.
