Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561002, here are decompositions:

61 + 560941 = 561002
73 + 560929 = 561002
109 + 560893 = 561002
139 + 560863 = 561002
199 + 560803 = 561002
241 + 560761 = 561002
283 + 560719 = 561002
313 + 560689 = 561002

Showing the first eight; more decompositions exist.
