Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531574, here are decompositions:

47 + 33531527 = 33531574
71 + 33531503 = 33531574
101 + 33531473 = 33531574
107 + 33531467 = 33531574
227 + 33531347 = 33531574
491 + 33531083 = 33531574
563 + 33531011 = 33531574
761 + 33530813 = 33531574

Showing the first eight; more decompositions exist.
