Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705528, here are decompositions:

37 + 8705491 = 8705528
61 + 8705467 = 8705528
67 + 8705461 = 8705528
79 + 8705449 = 8705528
109 + 8705419 = 8705528
229 + 8705299 = 8705528
379 + 8705149 = 8705528
487 + 8705041 = 8705528

Showing the first eight; more decompositions exist.
