Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654728, here are decompositions:

107 + 8654621 = 8654728
149 + 8654579 = 8654728
239 + 8654489 = 8654728
281 + 8654447 = 8654728
347 + 8654381 = 8654728
389 + 8654339 = 8654728
479 + 8654249 = 8654728
491 + 8654237 = 8654728

Showing the first eight; more decompositions exist.
