Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639348, here are decompositions:

97 + 8639251 = 8639348
199 + 8639149 = 8639348
229 + 8639119 = 8639348
241 + 8639107 = 8639348
337 + 8639011 = 8639348
349 + 8638999 = 8639348
397 + 8638951 = 8639348
439 + 8638909 = 8639348

Showing the first eight; more decompositions exist.
