Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581780, here are decompositions:

13 + 33581767 = 33581780
19 + 33581761 = 33581780
73 + 33581707 = 33581780
103 + 33581677 = 33581780
109 + 33581671 = 33581780
163 + 33581617 = 33581780
181 + 33581599 = 33581780
367 + 33581413 = 33581780

Showing the first eight; more decompositions exist.
