Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705538, here are decompositions:

7 + 8705531 = 8705538
11 + 8705527 = 8705538
19 + 8705519 = 8705538
31 + 8705507 = 8705538
47 + 8705491 = 8705538
71 + 8705467 = 8705538
89 + 8705449 = 8705538
97 + 8705441 = 8705538

Showing the first eight; more decompositions exist.
