Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992138, here are decompositions:

127 + 992011 = 992138
139 + 991999 = 992138
151 + 991987 = 992138
157 + 991981 = 992138
181 + 991957 = 992138
211 + 991927 = 992138
229 + 991909 = 992138
271 + 991867 = 992138

Showing the first eight; more decompositions exist.
