Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712666, here are decompositions:

5 + 8712661 = 8712666
37 + 8712629 = 8712666
89 + 8712577 = 8712666
269 + 8712397 = 8712666
293 + 8712373 = 8712666
317 + 8712349 = 8712666
359 + 8712307 = 8712666
373 + 8712293 = 8712666

Showing the first eight; more decompositions exist.
