Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553840, here are decompositions:

3 + 553837 = 553840
29 + 553811 = 553840
71 + 553769 = 553840
83 + 553757 = 553840
107 + 553733 = 553840
113 + 553727 = 553840
137 + 553703 = 553840
173 + 553667 = 553840

Showing the first eight; more decompositions exist.
