Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731524, here are decompositions:

13 + 8731511 = 8731524
23 + 8731501 = 8731524
31 + 8731493 = 8731524
47 + 8731477 = 8731524
97 + 8731427 = 8731524
107 + 8731417 = 8731524
181 + 8731343 = 8731524
211 + 8731313 = 8731524

Showing the first eight; more decompositions exist.
