Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639508, here are decompositions:

47 + 8639461 = 8639508
67 + 8639441 = 8639508
107 + 8639401 = 8639508
127 + 8639381 = 8639508
257 + 8639251 = 8639508
281 + 8639227 = 8639508
331 + 8639177 = 8639508
337 + 8639171 = 8639508

Showing the first eight; more decompositions exist.
