Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555420, here are decompositions:

29 + 555391 = 555420
37 + 555383 = 555420
59 + 555361 = 555420
71 + 555349 = 555420
83 + 555337 = 555420
113 + 555307 = 555420
127 + 555293 = 555420
163 + 555257 = 555420

Showing the first eight; more decompositions exist.
