Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 587142, here are decompositions:

5 + 587137 = 587142
11 + 587131 = 587142
19 + 587123 = 587142
41 + 587101 = 587142
79 + 587063 = 587142
89 + 587053 = 587142
109 + 587033 = 587142
163 + 586979 = 587142

Showing the first eight; more decompositions exist.
