Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978956, here are decompositions:

73 + 978883 = 978956
103 + 978853 = 978956
157 + 978799 = 978956
229 + 978727 = 978956
313 + 978643 = 978956
337 + 978619 = 978956
499 + 978457 = 978956
607 + 978349 = 978956

Showing the first eight; more decompositions exist.
