Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637494, here are decompositions:

3 + 8637491 = 8637494
13 + 8637481 = 8637494
43 + 8637451 = 8637494
67 + 8637427 = 8637494
157 + 8637337 = 8637494
193 + 8637301 = 8637494
241 + 8637253 = 8637494
331 + 8637163 = 8637494

Showing the first eight; more decompositions exist.
