Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555570, here are decompositions:

13 + 555557 = 555570
47 + 555523 = 555570
79 + 555491 = 555570
83 + 555487 = 555570
109 + 555461 = 555570
131 + 555439 = 555570
149 + 555421 = 555570
151 + 555419 = 555570

Showing the first eight; more decompositions exist.
