Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644144, here are decompositions:

53 + 8644091 = 8644144
83 + 8644061 = 8644144
191 + 8643953 = 8644144
251 + 8643893 = 8644144
293 + 8643851 = 8644144
347 + 8643797 = 8644144
557 + 8643587 = 8644144
617 + 8643527 = 8644144

Showing the first eight; more decompositions exist.
