Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007538, here are decompositions:

11 + 1007527 = 1007538
19 + 1007519 = 1007538
41 + 1007497 = 1007538
71 + 1007467 = 1007538
79 + 1007459 = 1007538
97 + 1007441 = 1007538
109 + 1007429 = 1007538
137 + 1007401 = 1007538

Showing the first eight; more decompositions exist.
