Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507530, here are decompositions:

151 + 33507379 = 33507530
211 + 33507319 = 33507530
223 + 33507307 = 33507530
271 + 33507259 = 33507530
283 + 33507247 = 33507530
307 + 33507223 = 33507530
409 + 33507121 = 33507530
421 + 33507109 = 33507530

Showing the first eight; more decompositions exist.
