Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739470, here are decompositions:

7 + 8739463 = 8739470
37 + 8739433 = 8739470
73 + 8739397 = 8739470
79 + 8739391 = 8739470
139 + 8739331 = 8739470
277 + 8739193 = 8739470
283 + 8739187 = 8739470
307 + 8739163 = 8739470

Showing the first eight; more decompositions exist.
