Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620980, here are decompositions:

53 + 33620927 = 33620980
89 + 33620891 = 33620980
167 + 33620813 = 33620980
191 + 33620789 = 33620980
353 + 33620627 = 33620980
359 + 33620621 = 33620980
383 + 33620597 = 33620980
389 + 33620591 = 33620980

Showing the first eight; more decompositions exist.
