Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33570972, here are decompositions:

23 + 33570949 = 33570972
53 + 33570919 = 33570972
73 + 33570899 = 33570972
89 + 33570883 = 33570972
101 + 33570871 = 33570972
139 + 33570833 = 33570972
163 + 33570809 = 33570972
179 + 33570793 = 33570972

Showing the first eight; more decompositions exist.
