Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739210, here are decompositions:

13 + 8739197 = 8739210
17 + 8739193 = 8739210
23 + 8739187 = 8739210
41 + 8739169 = 8739210
43 + 8739167 = 8739210
47 + 8739163 = 8739210
83 + 8739127 = 8739210
97 + 8739113 = 8739210

Showing the first eight; more decompositions exist.
