Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710280, here are decompositions:

3 + 8710277 = 8710280
31 + 8710249 = 8710280
37 + 8710243 = 8710280
67 + 8710213 = 8710280
223 + 8710057 = 8710280
307 + 8709973 = 8710280
349 + 8709931 = 8710280
367 + 8709913 = 8710280

Showing the first eight; more decompositions exist.
