Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488978, here are decompositions:

31 + 33488947 = 33488978
109 + 33488869 = 33488978
199 + 33488779 = 33488978
331 + 33488647 = 33488978
379 + 33488599 = 33488978
409 + 33488569 = 33488978
421 + 33488557 = 33488978
487 + 33488491 = 33488978

Showing the first eight; more decompositions exist.
