Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728936, here are decompositions:

53 + 8728883 = 8728936
113 + 8728823 = 8728936
149 + 8728787 = 8728936
179 + 8728757 = 8728936
257 + 8728679 = 8728936
479 + 8728457 = 8728936
509 + 8728427 = 8728936
563 + 8728373 = 8728936

Showing the first eight; more decompositions exist.
