Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 587138, here are decompositions:

7 + 587131 = 587138
31 + 587107 = 587138
37 + 587101 = 587138
157 + 586981 = 587138
199 + 586939 = 587138
229 + 586909 = 587138
241 + 586897 = 587138
337 + 586801 = 587138

Showing the first eight; more decompositions exist.
