Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531204, here are decompositions:

41 + 31531163 = 31531204
227 + 31530977 = 31531204
311 + 31530893 = 31531204
431 + 31530773 = 31531204
491 + 31530713 = 31531204
503 + 31530701 = 31531204
521 + 31530683 = 31531204
563 + 31530641 = 31531204

Showing the first eight; more decompositions exist.
