Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600420, here are decompositions:

61 + 8600359 = 8600420
79 + 8600341 = 8600420
97 + 8600323 = 8600420
181 + 8600239 = 8600420
277 + 8600143 = 8600420
331 + 8600089 = 8600420
349 + 8600071 = 8600420
373 + 8600047 = 8600420

Showing the first eight; more decompositions exist.
