Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981876, here are decompositions:

53 + 981823 = 981876
59 + 981817 = 981876
67 + 981809 = 981876
79 + 981797 = 981876
107 + 981769 = 981876
163 + 981713 = 981876
173 + 981703 = 981876
179 + 981697 = 981876

Showing the first eight; more decompositions exist.
