Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600390, here are decompositions:

31 + 8600359 = 8600390
67 + 8600323 = 8600390
151 + 8600239 = 8600390
157 + 8600233 = 8600390
229 + 8600161 = 8600390
349 + 8600041 = 8600390
367 + 8600023 = 8600390
397 + 8599993 = 8600390

Showing the first eight; more decompositions exist.
