Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708228, here are decompositions:

31 + 8708197 = 8708228
127 + 8708101 = 8708228
157 + 8708071 = 8708228
211 + 8708017 = 8708228
229 + 8707999 = 8708228
349 + 8707879 = 8708228
367 + 8707861 = 8708228
541 + 8707687 = 8708228

Showing the first eight; more decompositions exist.
