Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634642, here are decompositions:

13 + 8634629 = 8634642
61 + 8634581 = 8634642
103 + 8634539 = 8634642
139 + 8634503 = 8634642
173 + 8634469 = 8634642
193 + 8634449 = 8634642
229 + 8634413 = 8634642
251 + 8634391 = 8634642

Showing the first eight; more decompositions exist.
