Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513140, here are decompositions:

3 + 513137 = 513140
31 + 513109 = 513140
37 + 513103 = 513140
73 + 513067 = 513140
109 + 513031 = 513140
127 + 513013 = 513140
139 + 513001 = 513140
151 + 512989 = 513140

Showing the first eight; more decompositions exist.
