Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031938, here are decompositions:

101 + 1031837 = 1031938
107 + 1031831 = 1031938
179 + 1031759 = 1031938
197 + 1031741 = 1031938
269 + 1031669 = 1031938
389 + 1031549 = 1031938
431 + 1031507 = 1031938
449 + 1031489 = 1031938

Showing the first eight; more decompositions exist.
