Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138534, here are decompositions:

17 + 138517 = 138534
23 + 138511 = 138534
37 + 138497 = 138534
41 + 138493 = 138534
73 + 138461 = 138534
83 + 138451 = 138534
101 + 138433 = 138534
107 + 138427 = 138534

Showing the first eight; more decompositions exist.
