Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738436, here are decompositions:

29 + 8738407 = 8738436
37 + 8738399 = 8738436
53 + 8738383 = 8738436
59 + 8738377 = 8738436
73 + 8738363 = 8738436
97 + 8738339 = 8738436
103 + 8738333 = 8738436
137 + 8738299 = 8738436

Showing the first eight; more decompositions exist.
