Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538678, here are decompositions:

29 + 538649 = 538678
89 + 538589 = 538678
149 + 538529 = 538678
167 + 538511 = 538678
191 + 538487 = 538678
197 + 538481 = 538678
281 + 538397 = 538678
311 + 538367 = 538678

Showing the first eight; more decompositions exist.
