Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487172, here are decompositions:

139 + 33487033 = 33487172
151 + 33487021 = 33487172
331 + 33486841 = 33487172
373 + 33486799 = 33487172
409 + 33486763 = 33487172
421 + 33486751 = 33487172
769 + 33486403 = 33487172
811 + 33486361 = 33487172

Showing the first eight; more decompositions exist.
