Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537380, here are decompositions:

67 + 33537313 = 33537380
181 + 33537199 = 33537380
193 + 33537187 = 33537380
277 + 33537103 = 33537380
397 + 33536983 = 33537380
439 + 33536941 = 33537380
571 + 33536809 = 33537380
673 + 33536707 = 33537380

Showing the first eight; more decompositions exist.
