Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555388, here are decompositions:

5 + 555383 = 555388
101 + 555287 = 555388
131 + 555257 = 555388
137 + 555251 = 555388
167 + 555221 = 555388
179 + 555209 = 555388
269 + 555119 = 555388
311 + 555077 = 555388

Showing the first eight; more decompositions exist.
