Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531972, here are decompositions:

41 + 33531931 = 33531972
43 + 33531929 = 33531972
53 + 33531919 = 33531972
59 + 33531913 = 33531972
83 + 33531889 = 33531972
179 + 33531793 = 33531972
181 + 33531791 = 33531972
191 + 33531781 = 33531972

Showing the first eight; more decompositions exist.
