Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690994, here are decompositions:

23 + 8690971 = 8690994
31 + 8690963 = 8690994
41 + 8690953 = 8690994
43 + 8690951 = 8690994
47 + 8690947 = 8690994
73 + 8690921 = 8690994
127 + 8690867 = 8690994
167 + 8690827 = 8690994

Showing the first eight; more decompositions exist.
