Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637204, here are decompositions:

41 + 8637163 = 8637204
53 + 8637151 = 8637204
71 + 8637133 = 8637204
73 + 8637131 = 8637204
97 + 8637107 = 8637204
101 + 8637103 = 8637204
113 + 8637091 = 8637204
137 + 8637067 = 8637204

Showing the first eight; more decompositions exist.
