Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634618, here are decompositions:

37 + 8634581 = 8634618
61 + 8634557 = 8634618
67 + 8634551 = 8634618
79 + 8634539 = 8634618
101 + 8634517 = 8634618
137 + 8634481 = 8634618
149 + 8634469 = 8634618
151 + 8634467 = 8634618

Showing the first eight; more decompositions exist.
