Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553640, here are decompositions:

13 + 553627 = 553640
67 + 553573 = 553640
79 + 553561 = 553640
97 + 553543 = 553640
127 + 553513 = 553640
193 + 553447 = 553640
223 + 553417 = 553640
229 + 553411 = 553640

Showing the first eight; more decompositions exist.
