Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731548, here are decompositions:

17 + 8731531 = 8731548
19 + 8731529 = 8731548
37 + 8731511 = 8731548
47 + 8731501 = 8731548
71 + 8731477 = 8731548
101 + 8731447 = 8731548
131 + 8731417 = 8731548
167 + 8731381 = 8731548

Showing the first eight; more decompositions exist.
