Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761666, here are decompositions:

47 + 8761619 = 8761666
149 + 8761517 = 8761666
197 + 8761469 = 8761666
227 + 8761439 = 8761666
233 + 8761433 = 8761666
509 + 8761157 = 8761666
587 + 8761079 = 8761666
647 + 8761019 = 8761666

Showing the first eight; more decompositions exist.
