Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639962, here are decompositions:

11 + 8639951 = 8639962
41 + 8639921 = 8639962
53 + 8639909 = 8639962
59 + 8639903 = 8639962
113 + 8639849 = 8639962
251 + 8639711 = 8639962
431 + 8639531 = 8639962
503 + 8639459 = 8639962

Showing the first eight; more decompositions exist.
