Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507990, here are decompositions:

53 + 33507937 = 33507990
67 + 33507923 = 33507990
79 + 33507911 = 33507990
83 + 33507907 = 33507990
97 + 33507893 = 33507990
101 + 33507889 = 33507990
137 + 33507853 = 33507990
181 + 33507809 = 33507990

Showing the first eight; more decompositions exist.
