Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701584, here are decompositions:

7 + 8701577 = 8701584
13 + 8701571 = 8701584
53 + 8701531 = 8701584
107 + 8701477 = 8701584
127 + 8701457 = 8701584
137 + 8701447 = 8701584
181 + 8701403 = 8701584
193 + 8701391 = 8701584

Showing the first eight; more decompositions exist.
