Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524926, here are decompositions:

163 + 31524763 = 31524926
283 + 31524643 = 31524926
409 + 31524517 = 31524926
457 + 31524469 = 31524926
523 + 31524403 = 31524926
733 + 31524193 = 31524926
877 + 31524049 = 31524926
883 + 31524043 = 31524926

Showing the first eight; more decompositions exist.
