Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487478, here are decompositions:

61 + 33487417 = 33487478
331 + 33487147 = 33487478
397 + 33487081 = 33487478
457 + 33487021 = 33487478
631 + 33486847 = 33487478
709 + 33486769 = 33487478
727 + 33486751 = 33487478
1009 + 33486469 = 33487478

Showing the first eight; more decompositions exist.
