Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515978, here are decompositions:

7 + 33515971 = 33515978
61 + 33515917 = 33515978
271 + 33515707 = 33515978
277 + 33515701 = 33515978
409 + 33515569 = 33515978
439 + 33515539 = 33515978
541 + 33515437 = 33515978
547 + 33515431 = 33515978

Showing the first eight; more decompositions exist.
