Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731618, here are decompositions:

11 + 8731607 = 8731618
47 + 8731571 = 8731618
89 + 8731529 = 8731618
107 + 8731511 = 8731618
191 + 8731427 = 8731618
317 + 8731301 = 8731618
431 + 8731187 = 8731618
479 + 8731139 = 8731618

Showing the first eight; more decompositions exist.
