Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687626, here are decompositions:

23 + 8687603 = 8687626
113 + 8687513 = 8687626
149 + 8687477 = 8687626
173 + 8687453 = 8687626
197 + 8687429 = 8687626
239 + 8687387 = 8687626
257 + 8687369 = 8687626
263 + 8687363 = 8687626

Showing the first eight; more decompositions exist.
