Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712658, here are decompositions:

29 + 8712629 = 8712658
47 + 8712611 = 8712658
167 + 8712491 = 8712658
347 + 8712311 = 8712658
389 + 8712269 = 8712658
401 + 8712257 = 8712658
431 + 8712227 = 8712658
491 + 8712167 = 8712658

Showing the first eight; more decompositions exist.
