Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637260, here are decompositions:

3 + 8637257 = 8637260
7 + 8637253 = 8637260
13 + 8637247 = 8637260
97 + 8637163 = 8637260
109 + 8637151 = 8637260
127 + 8637133 = 8637260
157 + 8637103 = 8637260
193 + 8637067 = 8637260

Showing the first eight; more decompositions exist.
