Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497870, here are decompositions:

73 + 33497797 = 33497870
97 + 33497773 = 33497870
199 + 33497671 = 33497870
277 + 33497593 = 33497870
421 + 33497449 = 33497870
457 + 33497413 = 33497870
613 + 33497257 = 33497870
619 + 33497251 = 33497870

Showing the first eight; more decompositions exist.
