Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537490, here are decompositions:

53 + 33537437 = 33537490
71 + 33537419 = 33537490
101 + 33537389 = 33537490
131 + 33537359 = 33537490
197 + 33537293 = 33537490
227 + 33537263 = 33537490
251 + 33537239 = 33537490
257 + 33537233 = 33537490

Showing the first eight; more decompositions exist.
