Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700520, here are decompositions:

47 + 8700473 = 8700520
53 + 8700467 = 8700520
71 + 8700449 = 8700520
89 + 8700431 = 8700520
113 + 8700407 = 8700520
137 + 8700383 = 8700520
167 + 8700353 = 8700520
233 + 8700287 = 8700520

Showing the first eight; more decompositions exist.
