Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29142, here are decompositions:

5 + 29137 = 29142
11 + 29131 = 29142
13 + 29129 = 29142
19 + 29123 = 29142
41 + 29101 = 29142
79 + 29063 = 29142
83 + 29059 = 29142
109 + 29033 = 29142

Showing the first eight; more decompositions exist.
