Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697572, here are decompositions:

61 + 8697511 = 8697572
73 + 8697499 = 8697572
139 + 8697433 = 8697572
193 + 8697379 = 8697572
229 + 8697343 = 8697572
271 + 8697301 = 8697572
409 + 8697163 = 8697572
439 + 8697133 = 8697572

Showing the first eight; more decompositions exist.
