Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627042, here are decompositions:

149 + 31626893 = 31627042
173 + 31626869 = 31627042
353 + 31626689 = 31627042
479 + 31626563 = 31627042
509 + 31626533 = 31627042
653 + 31626389 = 31627042
659 + 31626383 = 31627042
683 + 31626359 = 31627042

Showing the first eight; more decompositions exist.
