Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555550, here are decompositions:

29 + 555521 = 555550
59 + 555491 = 555550
89 + 555461 = 555550
131 + 555419 = 555550
167 + 555383 = 555550
257 + 555293 = 555550
263 + 555287 = 555550
293 + 555257 = 555550

Showing the first eight; more decompositions exist.
