Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531388, here are decompositions:

41 + 33531347 = 33531388
89 + 33531299 = 33531388
311 + 33531077 = 33531388
389 + 33530999 = 33531388
419 + 33530969 = 33531388
599 + 33530789 = 33531388
647 + 33530741 = 33531388
659 + 33530729 = 33531388

Showing the first eight; more decompositions exist.
