Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708138, here are decompositions:

37 + 8708101 = 8708138
67 + 8708071 = 8708138
139 + 8707999 = 8708138
199 + 8707939 = 8708138
277 + 8707861 = 8708138
487 + 8707651 = 8708138
547 + 8707591 = 8708138
601 + 8707537 = 8708138

Showing the first eight; more decompositions exist.
