Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700538, here are decompositions:

17 + 8700521 = 8700538
71 + 8700467 = 8700538
89 + 8700449 = 8700538
107 + 8700431 = 8700538
131 + 8700407 = 8700538
137 + 8700401 = 8700538
239 + 8700299 = 8700538
251 + 8700287 = 8700538

Showing the first eight; more decompositions exist.
