Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507138, here are decompositions:

17 + 33507121 = 33507138
29 + 33507109 = 33507138
31 + 33507107 = 33507138
59 + 33507079 = 33507138
79 + 33507059 = 33507138
101 + 33507037 = 33507138
109 + 33507029 = 33507138
191 + 33506947 = 33507138

Showing the first eight; more decompositions exist.
