Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978854, here are decompositions:

3 + 978851 = 978854
127 + 978727 = 978854
157 + 978697 = 978854
211 + 978643 = 978854
313 + 978541 = 978854
397 + 978457 = 978854
571 + 978283 = 978854
577 + 978277 = 978854

Showing the first eight; more decompositions exist.
