Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637298, here are decompositions:

41 + 8637257 = 8637298
71 + 8637227 = 8637298
167 + 8637131 = 8637298
179 + 8637119 = 8637298
191 + 8637107 = 8637298
239 + 8637059 = 8637298
281 + 8637017 = 8637298
311 + 8636987 = 8637298

Showing the first eight; more decompositions exist.
