Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731534, here are decompositions:

3 + 8731531 = 8731534
5 + 8731529 = 8731534
23 + 8731511 = 8731534
41 + 8731493 = 8731534
101 + 8731433 = 8731534
107 + 8731427 = 8731534
191 + 8731343 = 8731534
233 + 8731301 = 8731534

Showing the first eight; more decompositions exist.
