Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702530, here are decompositions:

41 + 8702489 = 8702530
47 + 8702483 = 8702530
71 + 8702459 = 8702530
197 + 8702333 = 8702530
251 + 8702279 = 8702530
467 + 8702063 = 8702530
479 + 8702051 = 8702530
521 + 8702009 = 8702530

Showing the first eight; more decompositions exist.
