Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623152, here are decompositions:

11 + 8623141 = 8623152
29 + 8623123 = 8623152
71 + 8623081 = 8623152
79 + 8623073 = 8623152
101 + 8623051 = 8623152
113 + 8623039 = 8623152
149 + 8623003 = 8623152
179 + 8622973 = 8623152

Showing the first eight; more decompositions exist.
