Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978454, here are decompositions:

5 + 978449 = 978454
41 + 978413 = 978454
107 + 978347 = 978454
131 + 978323 = 978454
167 + 978287 = 978454
251 + 978203 = 978454
383 + 978071 = 978454
401 + 978053 = 978454

Showing the first eight; more decompositions exist.
