Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716442, here are decompositions:

3 + 8716439 = 8716442
13 + 8716429 = 8716442
61 + 8716381 = 8716442
193 + 8716249 = 8716442
199 + 8716243 = 8716442
223 + 8716219 = 8716442
283 + 8716159 = 8716442
373 + 8716069 = 8716442

Showing the first eight; more decompositions exist.
