Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581806, here are decompositions:

113 + 33581693 = 33581806
233 + 33581573 = 33581806
509 + 33581297 = 33581806
659 + 33581147 = 33581806
683 + 33581123 = 33581806
719 + 33581087 = 33581806
887 + 33580919 = 33581806
1019 + 33580787 = 33581806

Showing the first eight; more decompositions exist.
