Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555678, here are decompositions:

7 + 555671 = 555678
17 + 555661 = 555678
41 + 555637 = 555678
89 + 555589 = 555678
157 + 555521 = 555678
191 + 555487 = 555678
239 + 555439 = 555678
257 + 555421 = 555678

Showing the first eight; more decompositions exist.
