Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992172, here are decompositions:

19 + 992153 = 992172
31 + 992141 = 992172
43 + 992129 = 992172
59 + 992113 = 992172
61 + 992111 = 992172
149 + 992023 = 992172
151 + 992021 = 992172
173 + 991999 = 992172

Showing the first eight; more decompositions exist.
