Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481978, here are decompositions:

59 + 33481919 = 33481978
227 + 33481751 = 33481978
239 + 33481739 = 33481978
401 + 33481577 = 33481978
479 + 33481499 = 33481978
617 + 33481361 = 33481978
911 + 33481067 = 33481978
941 + 33481037 = 33481978

Showing the first eight; more decompositions exist.
