Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161862, here are decompositions:

23 + 161839 = 161862
31 + 161831 = 161862
79 + 161783 = 161862
83 + 161779 = 161862
89 + 161773 = 161862
101 + 161761 = 161862
109 + 161753 = 161862
131 + 161731 = 161862

Showing the first eight; more decompositions exist.
