Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550018, here are decompositions:

41 + 33549977 = 33550018
197 + 33549821 = 33550018
239 + 33549779 = 33550018
347 + 33549671 = 33550018
419 + 33549599 = 33550018
449 + 33549569 = 33550018
461 + 33549557 = 33550018
587 + 33549431 = 33550018

Showing the first eight; more decompositions exist.
