Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171862, here are decompositions:

11 + 171851 = 171862
59 + 171803 = 171862
101 + 171761 = 171862
149 + 171713 = 171862
191 + 171671 = 171862
233 + 171629 = 171862
389 + 171473 = 171862
461 + 171401 = 171862

Showing the first eight; more decompositions exist.
