Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 552818, here are decompositions:

31 + 552787 = 552818
61 + 552757 = 552818
67 + 552751 = 552818
109 + 552709 = 552818
229 + 552589 = 552818
307 + 552511 = 552818
337 + 552481 = 552818
349 + 552469 = 552818

Showing the first eight; more decompositions exist.
