Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505040, here are decompositions:

31 + 33505009 = 33505040
223 + 33504817 = 33505040
277 + 33504763 = 33505040
337 + 33504703 = 33505040
379 + 33504661 = 33505040
397 + 33504643 = 33505040
409 + 33504631 = 33505040
463 + 33504577 = 33505040

Showing the first eight; more decompositions exist.
