Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639992, here are decompositions:

5 + 8639987 = 8639992
41 + 8639951 = 8639992
71 + 8639921 = 8639992
83 + 8639909 = 8639992
89 + 8639903 = 8639992
173 + 8639819 = 8639992
239 + 8639753 = 8639992
281 + 8639711 = 8639992

Showing the first eight; more decompositions exist.
