Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992986, here are decompositions:

3 + 992983 = 992986
23 + 992963 = 992986
83 + 992903 = 992986
167 + 992819 = 992986
263 + 992723 = 992986
353 + 992633 = 992986
383 + 992603 = 992986
557 + 992429 = 992986

Showing the first eight; more decompositions exist.
