Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978632, here are decompositions:

13 + 978619 = 978632
229 + 978403 = 978632
283 + 978349 = 978632
349 + 978283 = 978632
409 + 978223 = 978632
541 + 978091 = 978632
601 + 978031 = 978632
631 + 978001 = 978632

Showing the first eight; more decompositions exist.
