Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731554, here are decompositions:

23 + 8731531 = 8731554
43 + 8731511 = 8731554
53 + 8731501 = 8731554
61 + 8731493 = 8731554
107 + 8731447 = 8731554
127 + 8731427 = 8731554
137 + 8731417 = 8731554
173 + 8731381 = 8731554

Showing the first eight; more decompositions exist.
