Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012538, here are decompositions:

19 + 1012519 = 1012538
31 + 1012507 = 1012538
127 + 1012411 = 1012538
139 + 1012399 = 1012538
271 + 1012267 = 1012538
277 + 1012261 = 1012538
337 + 1012201 = 1012538
349 + 1012189 = 1012538

Showing the first eight; more decompositions exist.
