Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490688, here are decompositions:

61 + 33490627 = 33490688
109 + 33490579 = 33490688
151 + 33490537 = 33490688
211 + 33490477 = 33490688
307 + 33490381 = 33490688
337 + 33490351 = 33490688
367 + 33490321 = 33490688
409 + 33490279 = 33490688

Showing the first eight; more decompositions exist.
