Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981574, here are decompositions:

5 + 981569 = 981574
47 + 981527 = 981574
101 + 981473 = 981574
107 + 981467 = 981574
131 + 981443 = 981574
137 + 981437 = 981574
197 + 981377 = 981574
263 + 981311 = 981574

Showing the first eight; more decompositions exist.
