Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553538, here are decompositions:

31 + 553507 = 553538
67 + 553471 = 553538
127 + 553411 = 553538
229 + 553309 = 553538
331 + 553207 = 553538
367 + 553171 = 553538
397 + 553141 = 553538
439 + 553099 = 553538

Showing the first eight; more decompositions exist.
