Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991892, here are decompositions:

3 + 991889 = 991892
19 + 991873 = 991892
151 + 991741 = 991892
199 + 991693 = 991892
229 + 991663 = 991892
241 + 991651 = 991892
271 + 991621 = 991892
313 + 991579 = 991892

Showing the first eight; more decompositions exist.
