Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708478, here are decompositions:

17 + 8708461 = 8708478
29 + 8708449 = 8708478
67 + 8708411 = 8708478
139 + 8708339 = 8708478
277 + 8708201 = 8708478
281 + 8708197 = 8708478
349 + 8708129 = 8708478
397 + 8708081 = 8708478

Showing the first eight; more decompositions exist.
