Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639464, here are decompositions:

3 + 8639461 = 8639464
5 + 8639459 = 8639464
11 + 8639453 = 8639464
23 + 8639441 = 8639464
83 + 8639381 = 8639464
101 + 8639363 = 8639464
173 + 8639291 = 8639464
191 + 8639273 = 8639464

Showing the first eight; more decompositions exist.
