Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637378, here are decompositions:

5 + 8637373 = 8637378
37 + 8637341 = 8637378
41 + 8637337 = 8637378
59 + 8637319 = 8637378
67 + 8637311 = 8637378
89 + 8637289 = 8637378
131 + 8637247 = 8637378
151 + 8637227 = 8637378

Showing the first eight; more decompositions exist.
