Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992140, here are decompositions:

11 + 992129 = 992140
29 + 992111 = 992140
53 + 992087 = 992140
89 + 992051 = 992140
167 + 991973 = 992140
179 + 991961 = 992140
197 + 991943 = 992140
239 + 991901 = 992140

Showing the first eight; more decompositions exist.
