Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509990, here are decompositions:

61 + 33509929 = 33509990
97 + 33509893 = 33509990
277 + 33509713 = 33509990
307 + 33509683 = 33509990
331 + 33509659 = 33509990
373 + 33509617 = 33509990
421 + 33509569 = 33509990
463 + 33509527 = 33509990

Showing the first eight; more decompositions exist.
