Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637192, here are decompositions:

13 + 8637179 = 8637192
29 + 8637163 = 8637192
41 + 8637151 = 8637192
59 + 8637133 = 8637192
61 + 8637131 = 8637192
73 + 8637119 = 8637192
89 + 8637103 = 8637192
101 + 8637091 = 8637192

Showing the first eight; more decompositions exist.
