Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738140, here are decompositions:

11 + 8738129 = 8738140
17 + 8738123 = 8738140
53 + 8738087 = 8738140
107 + 8738033 = 8738140
197 + 8737943 = 8738140
269 + 8737871 = 8738140
311 + 8737829 = 8738140
431 + 8737709 = 8738140

Showing the first eight; more decompositions exist.
