Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508438, here are decompositions:

137 + 33508301 = 33508438
149 + 33508289 = 33508438
311 + 33508127 = 33508438
347 + 33508091 = 33508438
419 + 33508019 = 33508438
449 + 33507989 = 33508438
617 + 33507821 = 33508438
641 + 33507797 = 33508438

Showing the first eight; more decompositions exist.
