Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978698, here are decompositions:

79 + 978619 = 978698
157 + 978541 = 978698
241 + 978457 = 978698
271 + 978427 = 978698
349 + 978349 = 978698
421 + 978277 = 978698
541 + 978157 = 978698
547 + 978151 = 978698

Showing the first eight; more decompositions exist.
