Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603842, here are decompositions:

3 + 8603839 = 8603842
11 + 8603831 = 8603842
29 + 8603813 = 8603842
89 + 8603753 = 8603842
113 + 8603729 = 8603842
131 + 8603711 = 8603842
179 + 8603663 = 8603842
239 + 8603603 = 8603842

Showing the first eight; more decompositions exist.
