Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708540, here are decompositions:

3 + 8708537 = 8708540
13 + 8708527 = 8708540
19 + 8708521 = 8708540
31 + 8708509 = 8708540
79 + 8708461 = 8708540
271 + 8708269 = 8708540
367 + 8708173 = 8708540
397 + 8708143 = 8708540

Showing the first eight; more decompositions exist.
