Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549490, here are decompositions:

59 + 33549431 = 33549490
113 + 33549377 = 33549490
131 + 33549359 = 33549490
137 + 33549353 = 33549490
167 + 33549323 = 33549490
179 + 33549311 = 33549490
239 + 33549251 = 33549490
251 + 33549239 = 33549490

Showing the first eight; more decompositions exist.
