Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623138, here are decompositions:

71 + 8623067 = 8623138
101 + 8623037 = 8623138
107 + 8623031 = 8623138
179 + 8622959 = 8623138
281 + 8622857 = 8623138
431 + 8622707 = 8623138
617 + 8622521 = 8623138
647 + 8622491 = 8623138

Showing the first eight; more decompositions exist.
