Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981292, here are decompositions:

3 + 981289 = 981292
5 + 981287 = 981292
29 + 981263 = 981292
71 + 981221 = 981292
83 + 981209 = 981292
269 + 981023 = 981292
281 + 981011 = 981292
293 + 980999 = 981292

Showing the first eight; more decompositions exist.
