Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550780, here are decompositions:

23 + 33550757 = 33550780
89 + 33550691 = 33550780
149 + 33550631 = 33550780
173 + 33550607 = 33550780
233 + 33550547 = 33550780
269 + 33550511 = 33550780
359 + 33550421 = 33550780
443 + 33550337 = 33550780

Showing the first eight; more decompositions exist.
