Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647144, here are decompositions:

5 + 8647139 = 8647144
17 + 8647127 = 8647144
53 + 8647091 = 8647144
83 + 8647061 = 8647144
101 + 8647043 = 8647144
113 + 8647031 = 8647144
137 + 8647007 = 8647144
173 + 8646971 = 8647144

Showing the first eight; more decompositions exist.
