Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8734820, here are decompositions:

13 + 8734807 = 8734820
19 + 8734801 = 8734820
79 + 8734741 = 8734820
181 + 8734639 = 8734820
277 + 8734543 = 8734820
307 + 8734513 = 8734820
313 + 8734507 = 8734820
337 + 8734483 = 8734820

Showing the first eight; more decompositions exist.
