Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555738, here are decompositions:

31 + 555707 = 555738
41 + 555697 = 555738
47 + 555691 = 555738
61 + 555677 = 555738
67 + 555671 = 555738
101 + 555637 = 555738
149 + 555589 = 555738
181 + 555557 = 555738

Showing the first eight; more decompositions exist.
