Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668444, here are decompositions:

23 + 8668421 = 8668444
41 + 8668403 = 8668444
251 + 8668193 = 8668444
293 + 8668151 = 8668444
311 + 8668133 = 8668444
383 + 8668061 = 8668444
401 + 8668043 = 8668444
443 + 8668001 = 8668444

Showing the first eight; more decompositions exist.
