Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601178, here are decompositions:

71 + 8601107 = 8601178
101 + 8601077 = 8601178
149 + 8601029 = 8601178
281 + 8600897 = 8601178
359 + 8600819 = 8601178
389 + 8600789 = 8601178
401 + 8600777 = 8601178
431 + 8600747 = 8601178

Showing the first eight; more decompositions exist.
