Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553906, here are decompositions:

5 + 553901 = 553906
137 + 553769 = 553906
149 + 553757 = 553906
173 + 553733 = 553906
179 + 553727 = 553906
239 + 553667 = 553906
257 + 553649 = 553906
263 + 553643 = 553906

Showing the first eight; more decompositions exist.
