Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661002, here are decompositions:

19 + 8660983 = 8661002
73 + 8660929 = 8661002
139 + 8660863 = 8661002
313 + 8660689 = 8661002
331 + 8660671 = 8661002
349 + 8660653 = 8661002
379 + 8660623 = 8661002
433 + 8660569 = 8661002

Showing the first eight; more decompositions exist.
