Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600428, here are decompositions:

17 + 8600411 = 8600428
29 + 8600399 = 8600428
197 + 8600231 = 8600428
257 + 8600171 = 8600428
461 + 8599967 = 8600428
467 + 8599961 = 8600428
761 + 8599667 = 8600428
821 + 8599607 = 8600428

Showing the first eight; more decompositions exist.
