Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31272, here are decompositions:

5 + 31267 = 31272
13 + 31259 = 31272
19 + 31253 = 31272
23 + 31249 = 31272
41 + 31231 = 31272
53 + 31219 = 31272
79 + 31193 = 31272
83 + 31189 = 31272

Showing the first eight; more decompositions exist.
