Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601978, here are decompositions:

167 + 33601811 = 33601978
281 + 33601697 = 33601978
419 + 33601559 = 33601978
467 + 33601511 = 33601978
491 + 33601487 = 33601978
569 + 33601409 = 33601978
659 + 33601319 = 33601978
701 + 33601277 = 33601978

Showing the first eight; more decompositions exist.
