Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738370, here are decompositions:

7 + 8738363 = 8738370
19 + 8738351 = 8738370
31 + 8738339 = 8738370
37 + 8738333 = 8738370
71 + 8738299 = 8738370
89 + 8738281 = 8738370
97 + 8738273 = 8738370
107 + 8738263 = 8738370

Showing the first eight; more decompositions exist.
