Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555660, here are decompositions:

23 + 555637 = 555660
67 + 555593 = 555660
71 + 555589 = 555660
103 + 555557 = 555660
137 + 555523 = 555660
139 + 555521 = 555660
173 + 555487 = 555660
199 + 555461 = 555660

Showing the first eight; more decompositions exist.
