Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735180, here are decompositions:

43 + 8735137 = 8735180
67 + 8735113 = 8735180
151 + 8735029 = 8735180
199 + 8734981 = 8735180
373 + 8734807 = 8735180
379 + 8734801 = 8735180
439 + 8734741 = 8735180
541 + 8734639 = 8735180

Showing the first eight; more decompositions exist.
