Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713212, here are decompositions:

19 + 8713193 = 8713212
31 + 8713181 = 8713212
71 + 8713141 = 8713212
89 + 8713123 = 8713212
103 + 8713109 = 8713212
199 + 8713013 = 8713212
239 + 8712973 = 8713212
281 + 8712931 = 8713212

Showing the first eight; more decompositions exist.
