Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978812, here are decompositions:

13 + 978799 = 978812
193 + 978619 = 978812
271 + 978541 = 978812
349 + 978463 = 978812
409 + 978403 = 978812
463 + 978349 = 978812
631 + 978181 = 978812
661 + 978151 = 978812

Showing the first eight; more decompositions exist.
