Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537986, here are decompositions:

67 + 33537919 = 33537986
277 + 33537709 = 33537986
373 + 33537613 = 33537986
397 + 33537589 = 33537986
457 + 33537529 = 33537986
463 + 33537523 = 33537986
577 + 33537409 = 33537986
673 + 33537313 = 33537986

Showing the first eight; more decompositions exist.
