Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992142, here are decompositions:

13 + 992129 = 992142
29 + 992113 = 992142
31 + 992111 = 992142
131 + 992011 = 992142
163 + 991979 = 992142
181 + 991961 = 992142
191 + 991951 = 992142
199 + 991943 = 992142

Showing the first eight; more decompositions exist.
