Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507972, here are decompositions:

59 + 33507913 = 33507972
61 + 33507911 = 33507972
73 + 33507899 = 33507972
79 + 33507893 = 33507972
83 + 33507889 = 33507972
151 + 33507821 = 33507972
163 + 33507809 = 33507972
191 + 33507781 = 33507972

Showing the first eight; more decompositions exist.
