Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738406, here are decompositions:

7 + 8738399 = 8738406
23 + 8738383 = 8738406
29 + 8738377 = 8738406
43 + 8738363 = 8738406
67 + 8738339 = 8738406
73 + 8738333 = 8738406
107 + 8738299 = 8738406
113 + 8738293 = 8738406

Showing the first eight; more decompositions exist.
