Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33580978, here are decompositions:

47 + 33580931 = 33580978
59 + 33580919 = 33580978
71 + 33580907 = 33580978
191 + 33580787 = 33580978
251 + 33580727 = 33580978
269 + 33580709 = 33580978
491 + 33580487 = 33580978
617 + 33580361 = 33580978

Showing the first eight; more decompositions exist.
