Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627926, here are decompositions:

23 + 31627903 = 31627926
37 + 31627889 = 31627926
47 + 31627879 = 31627926
163 + 31627763 = 31627926
173 + 31627753 = 31627926
199 + 31627727 = 31627926
277 + 31627649 = 31627926
349 + 31627577 = 31627926

Showing the first eight; more decompositions exist.
