Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738380, here are decompositions:

3 + 8738377 = 8738380
17 + 8738363 = 8738380
29 + 8738351 = 8738380
41 + 8738339 = 8738380
47 + 8738333 = 8738380
107 + 8738273 = 8738380
149 + 8738231 = 8738380
179 + 8738201 = 8738380

Showing the first eight; more decompositions exist.
