Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453622, here are decompositions:

139 + 31453483 = 31453622
229 + 31453393 = 31453622
373 + 31453249 = 31453622
463 + 31453159 = 31453622
601 + 31453021 = 31453622
829 + 31452793 = 31453622
853 + 31452769 = 31453622
859 + 31452763 = 31453622

Showing the first eight; more decompositions exist.
