Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978994, here are decompositions:

47 + 978947 = 978994
131 + 978863 = 978994
173 + 978821 = 978994
197 + 978797 = 978994
251 + 978743 = 978994
281 + 978713 = 978994
311 + 978683 = 978994
347 + 978647 = 978994

Showing the first eight; more decompositions exist.
