Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561132, here are decompositions:

23 + 561109 = 561132
29 + 561103 = 561132
31 + 561101 = 561132
41 + 561091 = 561132
53 + 561079 = 561132
71 + 561061 = 561132
73 + 561059 = 561132
79 + 561053 = 561132

Showing the first eight; more decompositions exist.
