Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013538, here are decompositions:

5 + 1013533 = 1013538
7 + 1013531 = 1013538
11 + 1013527 = 1013538
37 + 1013501 = 1013538
61 + 1013477 = 1013538
67 + 1013471 = 1013538
107 + 1013431 = 1013538
109 + 1013429 = 1013538

Showing the first eight; more decompositions exist.
