Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550990, here are decompositions:

23 + 33550967 = 33550990
41 + 33550949 = 33550990
59 + 33550931 = 33550990
191 + 33550799 = 33550990
233 + 33550757 = 33550990
359 + 33550631 = 33550990
383 + 33550607 = 33550990
443 + 33550547 = 33550990

Showing the first eight; more decompositions exist.
