Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992178, here are decompositions:

37 + 992141 = 992178
67 + 992111 = 992178
127 + 992051 = 992178
157 + 992021 = 992178
167 + 992011 = 992178
179 + 991999 = 992178
191 + 991987 = 992178
197 + 991981 = 992178

Showing the first eight; more decompositions exist.
