Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518660, here are decompositions:

37 + 33518623 = 33518660
73 + 33518587 = 33518660
163 + 33518497 = 33518660
211 + 33518449 = 33518660
223 + 33518437 = 33518660
271 + 33518389 = 33518660
367 + 33518293 = 33518660
421 + 33518239 = 33518660

Showing the first eight; more decompositions exist.
