Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639502, here are decompositions:

41 + 8639461 = 8639502
43 + 8639459 = 8639502
59 + 8639443 = 8639502
61 + 8639441 = 8639502
89 + 8639413 = 8639502
101 + 8639401 = 8639502
139 + 8639363 = 8639502
211 + 8639291 = 8639502

Showing the first eight; more decompositions exist.
