Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634442, here are decompositions:

29 + 8634413 = 8634442
59 + 8634383 = 8634442
71 + 8634371 = 8634442
83 + 8634359 = 8634442
191 + 8634251 = 8634442
239 + 8634203 = 8634442
263 + 8634179 = 8634442
269 + 8634173 = 8634442

Showing the first eight; more decompositions exist.
