Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601142, here are decompositions:

29 + 8601113 = 8601142
41 + 8601101 = 8601142
59 + 8601083 = 8601142
113 + 8601029 = 8601142
353 + 8600789 = 8601142
359 + 8600783 = 8601142
401 + 8600741 = 8601142
503 + 8600639 = 8601142

Showing the first eight; more decompositions exist.
