Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988812, here are decompositions:

23 + 988789 = 988812
29 + 988783 = 988812
53 + 988759 = 988812
79 + 988733 = 988812
101 + 988711 = 988812
131 + 988681 = 988812
151 + 988661 = 988812
163 + 988649 = 988812

Showing the first eight; more decompositions exist.
