Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487490, here are decompositions:

13 + 33487477 = 33487490
67 + 33487423 = 33487490
73 + 33487417 = 33487490
97 + 33487393 = 33487490
103 + 33487387 = 33487490
181 + 33487309 = 33487490
229 + 33487261 = 33487490
271 + 33487219 = 33487490

Showing the first eight; more decompositions exist.
