Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641246, here are decompositions:

59 + 8641187 = 8641246
113 + 8641133 = 8641246
149 + 8641097 = 8641246
167 + 8641079 = 8641246
239 + 8641007 = 8641246
269 + 8640977 = 8641246
359 + 8640887 = 8641246
479 + 8640767 = 8641246

Showing the first eight; more decompositions exist.
