Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487142, here are decompositions:

61 + 33487081 = 33487142
109 + 33487033 = 33487142
313 + 33486829 = 33487142
373 + 33486769 = 33487142
379 + 33486763 = 33487142
439 + 33486703 = 33487142
673 + 33486469 = 33487142
739 + 33486403 = 33487142

Showing the first eight; more decompositions exist.
