Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561028, here are decompositions:

59 + 560969 = 561028
89 + 560939 = 561028
131 + 560897 = 561028
137 + 560891 = 561028
191 + 560837 = 561028
257 + 560771 = 561028
359 + 560669 = 561028
389 + 560639 = 561028

Showing the first eight; more decompositions exist.
