Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619820, here are decompositions:

19 + 33619801 = 33619820
67 + 33619753 = 33619820
139 + 33619681 = 33619820
151 + 33619669 = 33619820
193 + 33619627 = 33619820
349 + 33619471 = 33619820
379 + 33619441 = 33619820
523 + 33619297 = 33619820

Showing the first eight; more decompositions exist.
