Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992218, here are decompositions:

89 + 992129 = 992218
107 + 992111 = 992218
131 + 992087 = 992218
167 + 992051 = 992218
197 + 992021 = 992218
239 + 991979 = 992218
257 + 991961 = 992218
317 + 991901 = 992218

Showing the first eight; more decompositions exist.
