Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712664, here are decompositions:

3 + 8712661 = 8712664
53 + 8712611 = 8712664
131 + 8712533 = 8712664
167 + 8712497 = 8712664
173 + 8712491 = 8712664
293 + 8712371 = 8712664
353 + 8712311 = 8712664
383 + 8712281 = 8712664

Showing the first eight; more decompositions exist.
