Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636564, here are decompositions:

31 + 8636533 = 8636564
43 + 8636521 = 8636564
73 + 8636491 = 8636564
397 + 8636167 = 8636564
457 + 8636107 = 8636564
613 + 8635951 = 8636564
631 + 8635933 = 8636564
787 + 8635777 = 8636564

Showing the first eight; more decompositions exist.
