Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731528, here are decompositions:

17 + 8731511 = 8731528
101 + 8731427 = 8731528
227 + 8731301 = 8731528
251 + 8731277 = 8731528
317 + 8731211 = 8731528
389 + 8731139 = 8731528
419 + 8731109 = 8731528
431 + 8731097 = 8731528

Showing the first eight; more decompositions exist.
