Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561418, here are decompositions:

29 + 561389 = 561418
41 + 561377 = 561418
59 + 561359 = 561418
71 + 561347 = 561418
167 + 561251 = 561418
227 + 561191 = 561418
257 + 561161 = 561418
317 + 561101 = 561418

Showing the first eight; more decompositions exist.
