Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702186, here are decompositions:

7 + 8702179 = 8702186
13 + 8702173 = 8702186
37 + 8702149 = 8702186
79 + 8702107 = 8702186
313 + 8701873 = 8702186
373 + 8701813 = 8702186
397 + 8701789 = 8702186
439 + 8701747 = 8702186

Showing the first eight; more decompositions exist.
