Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690766, here are decompositions:

53 + 8690713 = 8690766
83 + 8690683 = 8690766
89 + 8690677 = 8690766
103 + 8690663 = 8690766
107 + 8690659 = 8690766
127 + 8690639 = 8690766
163 + 8690603 = 8690766
167 + 8690599 = 8690766

Showing the first eight; more decompositions exist.
