Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710072, here are decompositions:

11 + 8710061 = 8710072
29 + 8710043 = 8710072
101 + 8709971 = 8710072
113 + 8709959 = 8710072
131 + 8709941 = 8710072
233 + 8709839 = 8710072
251 + 8709821 = 8710072
353 + 8709719 = 8710072

Showing the first eight; more decompositions exist.
