Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735120, here are decompositions:

7 + 8735113 = 8735120
73 + 8735047 = 8735120
109 + 8735011 = 8735120
127 + 8734993 = 8735120
139 + 8734981 = 8735120
313 + 8734807 = 8735120
379 + 8734741 = 8735120
547 + 8734573 = 8735120

Showing the first eight; more decompositions exist.
