Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981718, here are decompositions:

5 + 981713 = 981718
11 + 981707 = 981718
131 + 981587 = 981718
149 + 981569 = 981718
191 + 981527 = 981718
251 + 981467 = 981718
281 + 981437 = 981718
431 + 981287 = 981718

Showing the first eight; more decompositions exist.
