Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997882, here are decompositions:

3 + 997879 = 997882
5 + 997877 = 997882
71 + 997811 = 997882
89 + 997793 = 997882
113 + 997769 = 997882
131 + 997751 = 997882
233 + 997649 = 997882
293 + 997589 = 997882

Showing the first eight; more decompositions exist.
