Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731458, here are decompositions:

11 + 8731447 = 8731458
31 + 8731427 = 8731458
41 + 8731417 = 8731458
89 + 8731369 = 8731458
137 + 8731321 = 8731458
149 + 8731309 = 8731458
157 + 8731301 = 8731458
181 + 8731277 = 8731458

Showing the first eight; more decompositions exist.
