Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705474, here are decompositions:

7 + 8705467 = 8705474
13 + 8705461 = 8705474
31 + 8705443 = 8705474
163 + 8705311 = 8705474
307 + 8705167 = 8705474
397 + 8705077 = 8705474
433 + 8705041 = 8705474
523 + 8704951 = 8705474

Showing the first eight; more decompositions exist.
