Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25142, here are decompositions:

31 + 25111 = 25142
109 + 25033 = 25142
163 + 24979 = 25142
199 + 24943 = 25142
223 + 24919 = 25142
283 + 24859 = 25142
349 + 24793 = 25142
379 + 24763 = 25142

Showing the first eight; more decompositions exist.
