Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981468, here are decompositions:

17 + 981451 = 981468
29 + 981439 = 981468
31 + 981437 = 981468
71 + 981397 = 981468
149 + 981319 = 981468
157 + 981311 = 981468
167 + 981301 = 981468
179 + 981289 = 981468

Showing the first eight; more decompositions exist.
