Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978634, here are decompositions:

17 + 978617 = 978634
23 + 978611 = 978634
113 + 978521 = 978634
311 + 978323 = 978634
347 + 978287 = 978634
401 + 978233 = 978634
431 + 978203 = 978634
521 + 978113 = 978634

Showing the first eight; more decompositions exist.
