Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487538, here are decompositions:

31 + 33487507 = 33487538
61 + 33487477 = 33487538
151 + 33487387 = 33487538
229 + 33487309 = 33487538
277 + 33487261 = 33487538
349 + 33487189 = 33487538
421 + 33487117 = 33487538
457 + 33487081 = 33487538

Showing the first eight; more decompositions exist.
