Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487160, here are decompositions:

13 + 33487147 = 33487160
43 + 33487117 = 33487160
79 + 33487081 = 33487160
127 + 33487033 = 33487160
139 + 33487021 = 33487160
163 + 33486997 = 33487160
313 + 33486847 = 33487160
331 + 33486829 = 33487160

Showing the first eight; more decompositions exist.
