Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101586, here are decompositions:

5 + 101581 = 101586
13 + 101573 = 101586
53 + 101533 = 101586
59 + 101527 = 101586
73 + 101513 = 101586
83 + 101503 = 101586
97 + 101489 = 101586
103 + 101483 = 101586

Showing the first eight; more decompositions exist.
