Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29140, here are decompositions:

3 + 29137 = 29140
11 + 29129 = 29140
17 + 29123 = 29140
107 + 29033 = 29140
113 + 29027 = 29140
131 + 29009 = 29140
179 + 28961 = 29140
191 + 28949 = 29140

Showing the first eight; more decompositions exist.
