Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515972, here are decompositions:

79 + 33515893 = 33515972
109 + 33515863 = 33515972
199 + 33515773 = 33515972
271 + 33515701 = 33515972
379 + 33515593 = 33515972
433 + 33515539 = 33515972
463 + 33515509 = 33515972
499 + 33515473 = 33515972

Showing the first eight; more decompositions exist.
