Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56142, here are decompositions:

11 + 56131 = 56142
19 + 56123 = 56142
29 + 56113 = 56142
41 + 56101 = 56142
43 + 56099 = 56142
61 + 56081 = 56142
89 + 56053 = 56142
101 + 56041 = 56142

Showing the first eight; more decompositions exist.
