Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735420, here are decompositions:

3 + 8735417 = 8735420
7 + 8735413 = 8735420
61 + 8735359 = 8735420
73 + 8735347 = 8735420
79 + 8735341 = 8735420
223 + 8735197 = 8735420
241 + 8735179 = 8735420
283 + 8735137 = 8735420

Showing the first eight; more decompositions exist.
