Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553478, here are decompositions:

7 + 553471 = 553478
31 + 553447 = 553478
61 + 553417 = 553478
67 + 553411 = 553478
109 + 553369 = 553478
127 + 553351 = 553478
199 + 553279 = 553478
229 + 553249 = 553478

Showing the first eight; more decompositions exist.
