Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705472, here are decompositions:

5 + 8705467 = 8705472
11 + 8705461 = 8705472
19 + 8705453 = 8705472
23 + 8705449 = 8705472
29 + 8705443 = 8705472
31 + 8705441 = 8705472
43 + 8705429 = 8705472
53 + 8705419 = 8705472

Showing the first eight; more decompositions exist.
