Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507818, here are decompositions:

37 + 33507781 = 33507818
67 + 33507751 = 33507818
139 + 33507679 = 33507818
241 + 33507577 = 33507818
277 + 33507541 = 33507818
439 + 33507379 = 33507818
499 + 33507319 = 33507818
571 + 33507247 = 33507818

Showing the first eight; more decompositions exist.
