Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688994, here are decompositions:

3 + 8688991 = 8688994
131 + 8688863 = 8688994
383 + 8688611 = 8688994
401 + 8688593 = 8688994
443 + 8688551 = 8688994
467 + 8688527 = 8688994
557 + 8688437 = 8688994
641 + 8688353 = 8688994

Showing the first eight; more decompositions exist.
