Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639812, here are decompositions:

3 + 8639809 = 8639812
59 + 8639753 = 8639812
101 + 8639711 = 8639812
149 + 8639663 = 8639812
173 + 8639639 = 8639812
263 + 8639549 = 8639812
281 + 8639531 = 8639812
353 + 8639459 = 8639812

Showing the first eight; more decompositions exist.
