Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507912, here are decompositions:

5 + 33507907 = 33507912
13 + 33507899 = 33507912
19 + 33507893 = 33507912
23 + 33507889 = 33507912
59 + 33507853 = 33507912
103 + 33507809 = 33507912
131 + 33507781 = 33507912
149 + 33507763 = 33507912

Showing the first eight; more decompositions exist.
