Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531096, here are decompositions:

17 + 31531079 = 31531096
137 + 31530959 = 31531096
263 + 31530833 = 31531096
269 + 31530827 = 31531096
383 + 31530713 = 31531096
479 + 31530617 = 31531096
503 + 31530593 = 31531096
599 + 31530497 = 31531096

Showing the first eight; more decompositions exist.
