Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555558, here are decompositions:

37 + 555521 = 555558
67 + 555491 = 555558
71 + 555487 = 555558
97 + 555461 = 555558
137 + 555421 = 555558
139 + 555419 = 555558
167 + 555391 = 555558
197 + 555361 = 555558

Showing the first eight; more decompositions exist.
