Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711572, here are decompositions:

3 + 8711569 = 8711572
11 + 8711561 = 8711572
29 + 8711543 = 8711572
71 + 8711501 = 8711572
83 + 8711489 = 8711572
173 + 8711399 = 8711572
239 + 8711333 = 8711572
383 + 8711189 = 8711572

Showing the first eight; more decompositions exist.
