Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553988, here are decompositions:

7 + 553981 = 553988
67 + 553921 = 553988
139 + 553849 = 553988
151 + 553837 = 553988
199 + 553789 = 553988
229 + 553759 = 553988
241 + 553747 = 553988
307 + 553681 = 553988

Showing the first eight; more decompositions exist.
