Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731470, here are decompositions:

23 + 8731447 = 8731470
37 + 8731433 = 8731470
43 + 8731427 = 8731470
53 + 8731417 = 8731470
89 + 8731381 = 8731470
101 + 8731369 = 8731470
107 + 8731363 = 8731470
127 + 8731343 = 8731470

Showing the first eight; more decompositions exist.
