Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507438, here are decompositions:

31 + 33507407 = 33507438
37 + 33507401 = 33507438
59 + 33507379 = 33507438
61 + 33507377 = 33507438
79 + 33507359 = 33507438
131 + 33507307 = 33507438
179 + 33507259 = 33507438
191 + 33507247 = 33507438

Showing the first eight; more decompositions exist.
