Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470842, here are decompositions:

5 + 470837 = 470842
11 + 470831 = 470842
23 + 470819 = 470842
59 + 470783 = 470842
131 + 470711 = 470842
173 + 470669 = 470842
179 + 470663 = 470842
191 + 470651 = 470842

Showing the first eight; more decompositions exist.
