Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31854, here are decompositions:

5 + 31849 = 31854
7 + 31847 = 31854
37 + 31817 = 31854
61 + 31793 = 31854
83 + 31771 = 31854
103 + 31751 = 31854
113 + 31741 = 31854
127 + 31727 = 31854

Showing the first eight; more decompositions exist.
