Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553168, here are decompositions:

29 + 553139 = 553168
71 + 553097 = 553168
101 + 553067 = 553168
131 + 553037 = 553168
197 + 552971 = 553168
251 + 552917 = 553168
269 + 552899 = 553168
281 + 552887 = 553168

Showing the first eight; more decompositions exist.
