Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978982, here are decompositions:

131 + 978851 = 978982
233 + 978749 = 978982
239 + 978743 = 978982
269 + 978713 = 978982
293 + 978689 = 978982
383 + 978599 = 978982
461 + 978521 = 978982
491 + 978491 = 978982

Showing the first eight; more decompositions exist.
