Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639362, here are decompositions:

71 + 8639291 = 8639362
89 + 8639273 = 8639362
101 + 8639261 = 8639362
113 + 8639249 = 8639362
191 + 8639171 = 8639362
239 + 8639123 = 8639362
311 + 8639051 = 8639362
509 + 8638853 = 8639362

Showing the first eight; more decompositions exist.
