Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731576, here are decompositions:

5 + 8731571 = 8731576
47 + 8731529 = 8731576
83 + 8731493 = 8731576
149 + 8731427 = 8731576
233 + 8731343 = 8731576
263 + 8731313 = 8731576
389 + 8731187 = 8731576
467 + 8731109 = 8731576

Showing the first eight; more decompositions exist.
