Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507738, here are decompositions:

59 + 33507679 = 33507738
67 + 33507671 = 33507738
97 + 33507641 = 33507738
107 + 33507631 = 33507738
127 + 33507611 = 33507738
137 + 33507601 = 33507738
139 + 33507599 = 33507738
197 + 33507541 = 33507738

Showing the first eight; more decompositions exist.
