Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561156, here are decompositions:

47 + 561109 = 561156
53 + 561103 = 561156
59 + 561097 = 561156
73 + 561083 = 561156
97 + 561059 = 561156
103 + 561053 = 561156
109 + 561047 = 561156
137 + 561019 = 561156

Showing the first eight; more decompositions exist.
