Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553388, here are decompositions:

19 + 553369 = 553388
37 + 553351 = 553388
79 + 553309 = 553388
109 + 553279 = 553388
139 + 553249 = 553388
181 + 553207 = 553388
331 + 553057 = 553388
337 + 553051 = 553388

Showing the first eight; more decompositions exist.
