Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120858, here are decompositions:

7 + 120851 = 120858
11 + 120847 = 120858
29 + 120829 = 120858
41 + 120817 = 120858
47 + 120811 = 120858
79 + 120779 = 120858
109 + 120749 = 120858
137 + 120721 = 120858

Showing the first eight; more decompositions exist.
