Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717172, here are decompositions:

41 + 8717131 = 8717172
53 + 8717119 = 8717172
59 + 8717113 = 8717172
131 + 8717041 = 8717172
151 + 8717021 = 8717172
173 + 8716999 = 8717172
229 + 8716943 = 8717172
281 + 8716891 = 8717172

Showing the first eight; more decompositions exist.
