Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708538, here are decompositions:

11 + 8708527 = 8708538
17 + 8708521 = 8708538
19 + 8708519 = 8708538
29 + 8708509 = 8708538
31 + 8708507 = 8708538
37 + 8708501 = 8708538
89 + 8708449 = 8708538
109 + 8708429 = 8708538

Showing the first eight; more decompositions exist.
