Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522012, here are decompositions:

13 + 521999 = 522012
19 + 521993 = 522012
31 + 521981 = 522012
83 + 521929 = 522012
89 + 521923 = 522012
109 + 521903 = 522012
131 + 521881 = 522012
151 + 521861 = 522012

Showing the first eight; more decompositions exist.
