Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30140, here are decompositions:

3 + 30137 = 30140
7 + 30133 = 30140
31 + 30109 = 30140
37 + 30103 = 30140
43 + 30097 = 30140
127 + 30013 = 30140
151 + 29989 = 30140
157 + 29983 = 30140

Showing the first eight; more decompositions exist.
