Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981244, here are decompositions:

3 + 981241 = 981244
23 + 981221 = 981244
71 + 981173 = 981244
107 + 981137 = 981244
167 + 981077 = 981244
227 + 981017 = 981244
233 + 981011 = 981244
281 + 980963 = 981244

Showing the first eight; more decompositions exist.
