Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634538, here are decompositions:

41 + 8634497 = 8634538
71 + 8634467 = 8634538
89 + 8634449 = 8634538
167 + 8634371 = 8634538
179 + 8634359 = 8634538
191 + 8634347 = 8634538
239 + 8634299 = 8634538
359 + 8634179 = 8634538

Showing the first eight; more decompositions exist.
