Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637470, here are decompositions:

3 + 8637467 = 8637470
19 + 8637451 = 8637470
43 + 8637427 = 8637470
97 + 8637373 = 8637470
151 + 8637319 = 8637470
181 + 8637289 = 8637470
223 + 8637247 = 8637470
307 + 8637163 = 8637470

Showing the first eight; more decompositions exist.
