Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612940, here are decompositions:

13 + 8612927 = 8612940
47 + 8612893 = 8612940
67 + 8612873 = 8612940
79 + 8612861 = 8612940
101 + 8612839 = 8612940
103 + 8612837 = 8612940
109 + 8612831 = 8612940
139 + 8612801 = 8612940

Showing the first eight; more decompositions exist.
