Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553220, here are decompositions:

13 + 553207 = 553220
67 + 553153 = 553220
79 + 553141 = 553220
97 + 553123 = 553220
127 + 553093 = 553220
163 + 553057 = 553220
229 + 552991 = 553220
307 + 552913 = 553220

Showing the first eight; more decompositions exist.
