Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724628, here are decompositions:

131 + 8724497 = 8724628
149 + 8724479 = 8724628
167 + 8724461 = 8724628
191 + 8724437 = 8724628
251 + 8724377 = 8724628
257 + 8724371 = 8724628
281 + 8724347 = 8724628
317 + 8724311 = 8724628

Showing the first eight; more decompositions exist.
