Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640052, here are decompositions:

101 + 8639951 = 8640052
131 + 8639921 = 8640052
149 + 8639903 = 8640052
233 + 8639819 = 8640052
389 + 8639663 = 8640052
461 + 8639591 = 8640052
503 + 8639549 = 8640052
521 + 8639531 = 8640052

Showing the first eight; more decompositions exist.
