Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978902, here are decompositions:

19 + 978883 = 978902
31 + 978871 = 978902
103 + 978799 = 978902
283 + 978619 = 978902
439 + 978463 = 978902
499 + 978403 = 978902
619 + 978283 = 978902
751 + 978151 = 978902

Showing the first eight; more decompositions exist.
