Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620180, here are decompositions:

67 + 33620113 = 33620180
199 + 33619981 = 33620180
337 + 33619843 = 33620180
379 + 33619801 = 33620180
409 + 33619771 = 33620180
499 + 33619681 = 33620180
577 + 33619603 = 33620180
619 + 33619561 = 33620180

Showing the first eight; more decompositions exist.
