Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712842, here are decompositions:

181 + 8712661 = 8712842
241 + 8712601 = 8712842
421 + 8712421 = 8712842
613 + 8712229 = 8712842
661 + 8712181 = 8712842
673 + 8712169 = 8712842
709 + 8712133 = 8712842
751 + 8712091 = 8712842

Showing the first eight; more decompositions exist.
