Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115890, here are decompositions:

7 + 115883 = 115890
11 + 115879 = 115890
13 + 115877 = 115890
17 + 115873 = 115890
29 + 115861 = 115890
31 + 115859 = 115890
37 + 115853 = 115890
41 + 115849 = 115890

Showing the first eight; more decompositions exist.
