Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171994, here are decompositions:

47 + 171947 = 171994
71 + 171923 = 171994
113 + 171881 = 171994
131 + 171863 = 171994
167 + 171827 = 171994
191 + 171803 = 171994
233 + 171761 = 171994
281 + 171713 = 171994

Showing the first eight; more decompositions exist.
