Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992180, here are decompositions:

67 + 992113 = 992180
157 + 992023 = 992180
181 + 991999 = 992180
193 + 991987 = 992180
199 + 991981 = 992180
223 + 991957 = 992180
229 + 991951 = 992180
271 + 991909 = 992180

Showing the first eight; more decompositions exist.
