Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623144, here are decompositions:

3 + 8623141 = 8623144
41 + 8623103 = 8623144
71 + 8623073 = 8623144
83 + 8623061 = 8623144
107 + 8623037 = 8623144
113 + 8623031 = 8623144
461 + 8622683 = 8623144
653 + 8622491 = 8623144

Showing the first eight; more decompositions exist.
