Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701530, here are decompositions:

11 + 8701519 = 8701530
23 + 8701507 = 8701530
31 + 8701499 = 8701530
37 + 8701493 = 8701530
41 + 8701489 = 8701530
53 + 8701477 = 8701530
73 + 8701457 = 8701530
83 + 8701447 = 8701530

Showing the first eight; more decompositions exist.
