Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981412, here are decompositions:

101 + 981311 = 981412
149 + 981263 = 981412
191 + 981221 = 981412
239 + 981173 = 981412
389 + 981023 = 981412
401 + 981011 = 981412
449 + 980963 = 981412
491 + 980921 = 981412

Showing the first eight; more decompositions exist.
