Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507140, here are decompositions:

3 + 33507137 = 33507140
19 + 33507121 = 33507140
31 + 33507109 = 33507140
61 + 33507079 = 33507140
103 + 33507037 = 33507140
193 + 33506947 = 33507140
283 + 33506857 = 33507140
367 + 33506773 = 33507140

Showing the first eight; more decompositions exist.
