Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981472, here are decompositions:

5 + 981467 = 981472
29 + 981443 = 981472
53 + 981419 = 981472
251 + 981221 = 981472
263 + 981209 = 981472
449 + 981023 = 981472
461 + 981011 = 981472
509 + 980963 = 981472

Showing the first eight; more decompositions exist.
