Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553842, here are decompositions:

5 + 553837 = 553842
31 + 553811 = 553842
53 + 553789 = 553842
73 + 553769 = 553842
83 + 553759 = 553842
109 + 553733 = 553842
139 + 553703 = 553842
193 + 553649 = 553842

Showing the first eight; more decompositions exist.
