Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708842, here are decompositions:

11 + 8708831 = 8708842
101 + 8708741 = 8708842
179 + 8708663 = 8708842
251 + 8708591 = 8708842
419 + 8708423 = 8708842
431 + 8708411 = 8708842
449 + 8708393 = 8708842
503 + 8708339 = 8708842

Showing the first eight; more decompositions exist.
