Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538020, here are decompositions:

19 + 538001 = 538020
29 + 537991 = 538020
79 + 537941 = 538020
101 + 537919 = 538020
107 + 537913 = 538020
137 + 537883 = 538020
167 + 537853 = 538020
173 + 537847 = 538020

Showing the first eight; more decompositions exist.
