Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86874, here are decompositions:

5 + 86869 = 86874
13 + 86861 = 86874
17 + 86857 = 86874
23 + 86851 = 86874
31 + 86843 = 86874
37 + 86837 = 86874
61 + 86813 = 86874
103 + 86771 = 86874

Showing the first eight; more decompositions exist.
