Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561090, here are decompositions:

7 + 561083 = 561090
11 + 561079 = 561090
29 + 561061 = 561090
31 + 561059 = 561090
37 + 561053 = 561090
43 + 561047 = 561090
71 + 561019 = 561090
113 + 560977 = 561090

Showing the first eight; more decompositions exist.
