Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537478, here are decompositions:

41 + 33537437 = 33537478
59 + 33537419 = 33537478
89 + 33537389 = 33537478
239 + 33537239 = 33537478
251 + 33537227 = 33537478
311 + 33537167 = 33537478
389 + 33537089 = 33537478
431 + 33537047 = 33537478

Showing the first eight; more decompositions exist.
