Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738382, here are decompositions:

5 + 8738377 = 8738382
19 + 8738363 = 8738382
31 + 8738351 = 8738382
43 + 8738339 = 8738382
83 + 8738299 = 8738382
89 + 8738293 = 8738382
101 + 8738281 = 8738382
109 + 8738273 = 8738382

Showing the first eight; more decompositions exist.
