Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612874, here are decompositions:

13 + 8612861 = 8612874
37 + 8612837 = 8612874
43 + 8612831 = 8612874
73 + 8612801 = 8612874
97 + 8612777 = 8612874
107 + 8612767 = 8612874
131 + 8612743 = 8612874
163 + 8612711 = 8612874

Showing the first eight; more decompositions exist.
