Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712668, here are decompositions:

7 + 8712661 = 8712668
67 + 8712601 = 8712668
271 + 8712397 = 8712668
331 + 8712337 = 8712668
409 + 8712259 = 8712668
439 + 8712229 = 8712668
487 + 8712181 = 8712668
499 + 8712169 = 8712668

Showing the first eight; more decompositions exist.
