Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739240, here are decompositions:

31 + 8739209 = 8739240
43 + 8739197 = 8739240
47 + 8739193 = 8739240
53 + 8739187 = 8739240
71 + 8739169 = 8739240
73 + 8739167 = 8739240
113 + 8739127 = 8739240
127 + 8739113 = 8739240

Showing the first eight; more decompositions exist.
