Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612844, here are decompositions:

5 + 8612839 = 8612844
7 + 8612837 = 8612844
13 + 8612831 = 8612844
43 + 8612801 = 8612844
67 + 8612777 = 8612844
101 + 8612743 = 8612844
113 + 8612731 = 8612844
131 + 8612713 = 8612844

Showing the first eight; more decompositions exist.
