Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84874, here are decompositions:

3 + 84871 = 84874
5 + 84869 = 84874
17 + 84857 = 84874
47 + 84827 = 84874
113 + 84761 = 84874
137 + 84737 = 84874
173 + 84701 = 84874
353 + 84521 = 84874

Showing the first eight; more decompositions exist.
