Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731412, here are decompositions:

31 + 8731381 = 8731412
43 + 8731369 = 8731412
73 + 8731339 = 8731412
103 + 8731309 = 8731412
163 + 8731249 = 8731412
181 + 8731231 = 8731412
199 + 8731213 = 8731412
211 + 8731201 = 8731412

Showing the first eight; more decompositions exist.
