Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651766, here are decompositions:

29 + 8651737 = 8651766
43 + 8651723 = 8651766
73 + 8651693 = 8651766
83 + 8651683 = 8651766
103 + 8651663 = 8651766
127 + 8651639 = 8651766
139 + 8651627 = 8651766
157 + 8651609 = 8651766

Showing the first eight; more decompositions exist.
