Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632642, here are decompositions:

113 + 8632529 = 8632642
149 + 8632493 = 8632642
191 + 8632451 = 8632642
251 + 8632391 = 8632642
281 + 8632361 = 8632642
419 + 8632223 = 8632642
503 + 8632139 = 8632642
509 + 8632133 = 8632642

Showing the first eight; more decompositions exist.
