Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644042, here are decompositions:

23 + 8644019 = 8644042
83 + 8643959 = 8644042
89 + 8643953 = 8644042
101 + 8643941 = 8644042
149 + 8643893 = 8644042
191 + 8643851 = 8644042
263 + 8643779 = 8644042
293 + 8643749 = 8644042

Showing the first eight; more decompositions exist.
