Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553442, here are decompositions:

3 + 553439 = 553442
31 + 553411 = 553442
73 + 553369 = 553442
79 + 553363 = 553442
163 + 553279 = 553442
193 + 553249 = 553442
271 + 553171 = 553442
349 + 553093 = 553442

Showing the first eight; more decompositions exist.
