Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981922, here are decompositions:

3 + 981919 = 981922
113 + 981809 = 981922
191 + 981731 = 981922
239 + 981683 = 981922
269 + 981653 = 981922
353 + 981569 = 981922
449 + 981473 = 981922
479 + 981443 = 981922

Showing the first eight; more decompositions exist.
