Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978544, here are decompositions:

3 + 978541 = 978544
23 + 978521 = 978544
53 + 978491 = 978544
71 + 978473 = 978544
131 + 978413 = 978544
197 + 978347 = 978544
257 + 978287 = 978544
311 + 978233 = 978544

Showing the first eight; more decompositions exist.
