Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27142, here are decompositions:

83 + 27059 = 27142
131 + 27011 = 27142
149 + 26993 = 27142
191 + 26951 = 27142
239 + 26903 = 27142
251 + 26891 = 27142
263 + 26879 = 27142
281 + 26861 = 27142

Showing the first eight; more decompositions exist.
