Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636228, here are decompositions:

61 + 8636167 = 8636228
229 + 8635999 = 8636228
277 + 8635951 = 8636228
331 + 8635897 = 8636228
379 + 8635849 = 8636228
499 + 8635729 = 8636228
541 + 8635687 = 8636228
571 + 8635657 = 8636228

Showing the first eight; more decompositions exist.
