Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497138, here are decompositions:

67 + 33497071 = 33497138
109 + 33497029 = 33497138
229 + 33496909 = 33497138
277 + 33496861 = 33497138
487 + 33496651 = 33497138
547 + 33496591 = 33497138
607 + 33496531 = 33497138
709 + 33496429 = 33497138

Showing the first eight; more decompositions exist.
