Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507870, here are decompositions:

17 + 33507853 = 33507870
61 + 33507809 = 33507870
73 + 33507797 = 33507870
89 + 33507781 = 33507870
107 + 33507763 = 33507870
127 + 33507743 = 33507870
181 + 33507689 = 33507870
191 + 33507679 = 33507870

Showing the first eight; more decompositions exist.
