Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632742, here are decompositions:

43 + 8632699 = 8632742
163 + 8632579 = 8632742
211 + 8632531 = 8632742
229 + 8632513 = 8632742
331 + 8632411 = 8632742
379 + 8632363 = 8632742
409 + 8632333 = 8632742
439 + 8632303 = 8632742

Showing the first eight; more decompositions exist.
