Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531556, here are decompositions:

29 + 33531527 = 33531556
53 + 33531503 = 33531556
83 + 33531473 = 33531556
89 + 33531467 = 33531556
167 + 33531389 = 33531556
257 + 33531299 = 33531556
389 + 33531167 = 33531556
479 + 33531077 = 33531556

Showing the first eight; more decompositions exist.
