Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76666, here are decompositions:

17 + 76649 = 76666
59 + 76607 = 76666
173 + 76493 = 76666
179 + 76487 = 76666
263 + 76403 = 76666
383 + 76283 = 76666
503 + 76163 = 76666
509 + 76157 = 76666

Showing the first eight; more decompositions exist.
