Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561162, here are decompositions:

53 + 561109 = 561162
59 + 561103 = 561162
61 + 561101 = 561162
71 + 561091 = 561162
79 + 561083 = 561162
83 + 561079 = 561162
101 + 561061 = 561162
103 + 561059 = 561162

Showing the first eight; more decompositions exist.
