Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488420, here are decompositions:

13 + 33488407 = 33488420
67 + 33488353 = 33488420
109 + 33488311 = 33488420
139 + 33488281 = 33488420
283 + 33488137 = 33488420
313 + 33488107 = 33488420
373 + 33488047 = 33488420
379 + 33488041 = 33488420

Showing the first eight; more decompositions exist.
