Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981202, here are decompositions:

3 + 981199 = 981202
29 + 981173 = 981202
179 + 981023 = 981202
191 + 981011 = 981202
239 + 980963 = 981202
281 + 980921 = 981202
293 + 980909 = 981202
401 + 980801 = 981202

Showing the first eight; more decompositions exist.
