Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639994, here are decompositions:

7 + 8639987 = 8639994
17 + 8639977 = 8639994
43 + 8639951 = 8639994
71 + 8639923 = 8639994
73 + 8639921 = 8639994
131 + 8639863 = 8639994
157 + 8639837 = 8639994
191 + 8639803 = 8639994

Showing the first eight; more decompositions exist.
