Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656444, here are decompositions:

11 + 8656433 = 8656444
131 + 8656313 = 8656444
191 + 8656253 = 8656444
281 + 8656163 = 8656444
311 + 8656133 = 8656444
347 + 8656097 = 8656444
353 + 8656091 = 8656444
491 + 8655953 = 8656444

Showing the first eight; more decompositions exist.
