Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634420, here are decompositions:

7 + 8634413 = 8634420
23 + 8634397 = 8634420
29 + 8634391 = 8634420
37 + 8634383 = 8634420
61 + 8634359 = 8634420
73 + 8634347 = 8634420
167 + 8634253 = 8634420
241 + 8634179 = 8634420

Showing the first eight; more decompositions exist.
