Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619138, here are decompositions:

7 + 8619131 = 8619138
37 + 8619101 = 8619138
41 + 8619097 = 8619138
61 + 8619077 = 8619138
67 + 8619071 = 8619138
71 + 8619067 = 8619138
79 + 8619059 = 8619138
97 + 8619041 = 8619138

Showing the first eight; more decompositions exist.
