Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561402, here are decompositions:

13 + 561389 = 561402
29 + 561373 = 561402
43 + 561359 = 561402
59 + 561343 = 561402
89 + 561313 = 561402
151 + 561251 = 561402
173 + 561229 = 561402
211 + 561191 = 561402

Showing the first eight; more decompositions exist.
