Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700172, here are decompositions:

3 + 8700169 = 8700172
11 + 8700161 = 8700172
59 + 8700113 = 8700172
101 + 8700071 = 8700172
113 + 8700059 = 8700172
179 + 8699993 = 8700172
191 + 8699981 = 8700172
293 + 8699879 = 8700172

Showing the first eight; more decompositions exist.
