Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522072, here are decompositions:

11 + 522061 = 522072
13 + 522059 = 522072
73 + 521999 = 522072
79 + 521993 = 522072
149 + 521923 = 522072
191 + 521881 = 522072
193 + 521879 = 522072
211 + 521861 = 522072

Showing the first eight; more decompositions exist.
