Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637372, here are decompositions:

31 + 8637341 = 8637372
53 + 8637319 = 8637372
61 + 8637311 = 8637372
71 + 8637301 = 8637372
83 + 8637289 = 8637372
109 + 8637263 = 8637372
193 + 8637179 = 8637372
239 + 8637133 = 8637372

Showing the first eight; more decompositions exist.
