Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553318, here are decompositions:

41 + 553277 = 553318
89 + 553229 = 553318
107 + 553211 = 553318
137 + 553181 = 553318
179 + 553139 = 553318
251 + 553067 = 553318
281 + 553037 = 553318
347 + 552971 = 553318

Showing the first eight; more decompositions exist.
