Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577628, here are decompositions:

127 + 33577501 = 33577628
199 + 33577429 = 33577628
307 + 33577321 = 33577628
421 + 33577207 = 33577628
607 + 33577021 = 33577628
631 + 33576997 = 33577628
661 + 33576967 = 33577628
739 + 33576889 = 33577628

Showing the first eight; more decompositions exist.
