Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623146, here are decompositions:

5 + 8623141 = 8623146
23 + 8623123 = 8623146
43 + 8623103 = 8623146
73 + 8623073 = 8623146
79 + 8623067 = 8623146
107 + 8623039 = 8623146
109 + 8623037 = 8623146
113 + 8623033 = 8623146

Showing the first eight; more decompositions exist.
