Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687212, here are decompositions:

3 + 8687209 = 8687212
5 + 8687207 = 8687212
29 + 8687183 = 8687212
41 + 8687171 = 8687212
71 + 8687141 = 8687212
251 + 8686961 = 8687212
311 + 8686901 = 8687212
383 + 8686829 = 8687212

Showing the first eight; more decompositions exist.
