Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634490, here are decompositions:

23 + 8634467 = 8634490
41 + 8634449 = 8634490
107 + 8634383 = 8634490
131 + 8634359 = 8634490
191 + 8634299 = 8634490
239 + 8634251 = 8634490
257 + 8634233 = 8634490
311 + 8634179 = 8634490

Showing the first eight; more decompositions exist.
