Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528140, here are decompositions:

3 + 528137 = 528140
13 + 528127 = 528140
43 + 528097 = 528140
97 + 528043 = 528140
127 + 528013 = 528140
139 + 528001 = 528140
157 + 527983 = 528140
199 + 527941 = 528140

Showing the first eight; more decompositions exist.
