Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507812, here are decompositions:

3 + 33507809 = 33507812
31 + 33507781 = 33507812
61 + 33507751 = 33507812
181 + 33507631 = 33507812
211 + 33507601 = 33507812
271 + 33507541 = 33507812
433 + 33507379 = 33507812
601 + 33507211 = 33507812

Showing the first eight; more decompositions exist.
