Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84972, here are decompositions:

5 + 84967 = 84972
11 + 84961 = 84972
53 + 84919 = 84972
59 + 84913 = 84972
101 + 84871 = 84972
103 + 84869 = 84972
113 + 84859 = 84972
163 + 84809 = 84972

Showing the first eight; more decompositions exist.
