Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731658, here are decompositions:

31 + 8731627 = 8731658
79 + 8731579 = 8731658
127 + 8731531 = 8731658
157 + 8731501 = 8731658
181 + 8731477 = 8731658
211 + 8731447 = 8731658
241 + 8731417 = 8731658
277 + 8731381 = 8731658

Showing the first eight; more decompositions exist.
