Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491980, here are decompositions:

3 + 33491977 = 33491980
131 + 33491849 = 33491980
149 + 33491831 = 33491980
233 + 33491747 = 33491980
239 + 33491741 = 33491980
251 + 33491729 = 33491980
359 + 33491621 = 33491980
419 + 33491561 = 33491980

Showing the first eight; more decompositions exist.
