Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978964, here are decompositions:

17 + 978947 = 978964
47 + 978917 = 978964
101 + 978863 = 978964
113 + 978851 = 978964
167 + 978797 = 978964
191 + 978773 = 978964
251 + 978713 = 978964
281 + 978683 = 978964

Showing the first eight; more decompositions exist.
