Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556402, here are decompositions:

3 + 556399 = 556402
29 + 556373 = 556402
59 + 556343 = 556402
71 + 556331 = 556402
89 + 556313 = 556402
113 + 556289 = 556402
131 + 556271 = 556402
149 + 556253 = 556402

Showing the first eight; more decompositions exist.
