Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712486, here are decompositions:

89 + 8712397 = 8712486
113 + 8712373 = 8712486
137 + 8712349 = 8712486
149 + 8712337 = 8712486
163 + 8712323 = 8712486
179 + 8712307 = 8712486
193 + 8712293 = 8712486
199 + 8712287 = 8712486

Showing the first eight; more decompositions exist.
