Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551580, here are decompositions:

37 + 33551543 = 33551580
47 + 33551533 = 33551580
53 + 33551527 = 33551580
61 + 33551519 = 33551580
67 + 33551513 = 33551580
71 + 33551509 = 33551580
79 + 33551501 = 33551580
131 + 33551449 = 33551580

Showing the first eight; more decompositions exist.
