Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553138, here are decompositions:

41 + 553097 = 553138
71 + 553067 = 553138
101 + 553037 = 553138
167 + 552971 = 553138
239 + 552899 = 553138
251 + 552887 = 553138
317 + 552821 = 553138
347 + 552791 = 553138

Showing the first eight; more decompositions exist.
