Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951820, here are decompositions:

17 + 951803 = 951820
29 + 951791 = 951820
71 + 951749 = 951820
131 + 951689 = 951820
173 + 951647 = 951820
179 + 951641 = 951820
197 + 951623 = 951820
239 + 951581 = 951820

Showing the first eight; more decompositions exist.
