Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969642, here are decompositions:

5 + 969637 = 969642
43 + 969599 = 969642
73 + 969569 = 969642
83 + 969559 = 969642
109 + 969533 = 969642
139 + 969503 = 969642
181 + 969461 = 969642
199 + 969443 = 969642

Showing the first eight; more decompositions exist.
