Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688442, here are decompositions:

5 + 8688437 = 8688442
89 + 8688353 = 8688442
131 + 8688311 = 8688442
233 + 8688209 = 8688442
239 + 8688203 = 8688442
281 + 8688161 = 8688442
359 + 8688083 = 8688442
383 + 8688059 = 8688442

Showing the first eight; more decompositions exist.
