Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671842, here are decompositions:

5 + 8671837 = 8671842
31 + 8671811 = 8671842
73 + 8671769 = 8671842
103 + 8671739 = 8671842
131 + 8671711 = 8671842
173 + 8671669 = 8671842
211 + 8671631 = 8671842
269 + 8671573 = 8671842

Showing the first eight; more decompositions exist.
