Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102992, here are decompositions:

61 + 102931 = 102992
79 + 102913 = 102992
151 + 102841 = 102992
163 + 102829 = 102992
181 + 102811 = 102992
199 + 102793 = 102992
223 + 102769 = 102992
229 + 102763 = 102992

Showing the first eight; more decompositions exist.
