Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555650, here are decompositions:

13 + 555637 = 555650
61 + 555589 = 555650
127 + 555523 = 555650
163 + 555487 = 555650
211 + 555439 = 555650
229 + 555421 = 555650
313 + 555337 = 555650
349 + 555301 = 555650

Showing the first eight; more decompositions exist.
