Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687236, here are decompositions:

3 + 8687233 = 8687236
23 + 8687213 = 8687236
29 + 8687207 = 8687236
53 + 8687183 = 8687236
149 + 8687087 = 8687236
167 + 8687069 = 8687236
347 + 8686889 = 8687236
353 + 8686883 = 8687236

Showing the first eight; more decompositions exist.
