Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526018, here are decompositions:

71 + 525947 = 526018
131 + 525887 = 526018
149 + 525869 = 526018
179 + 525839 = 526018
347 + 525671 = 526018
419 + 525599 = 526018
557 + 525461 = 526018
587 + 525431 = 526018

Showing the first eight; more decompositions exist.
