Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624144, here are decompositions:

3 + 8624141 = 8624144
7 + 8624137 = 8624144
13 + 8624131 = 8624144
43 + 8624101 = 8624144
127 + 8624017 = 8624144
181 + 8623963 = 8624144
241 + 8623903 = 8624144
313 + 8623831 = 8624144

Showing the first eight; more decompositions exist.
