Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33579972, here are decompositions:

11 + 33579961 = 33579972
53 + 33579919 = 33579972
103 + 33579869 = 33579972
131 + 33579841 = 33579972
149 + 33579823 = 33579972
163 + 33579809 = 33579972
373 + 33579599 = 33579972
421 + 33579551 = 33579972

Showing the first eight; more decompositions exist.
