Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31302, here are decompositions:

31 + 31271 = 31302
43 + 31259 = 31302
53 + 31249 = 31302
71 + 31231 = 31302
79 + 31223 = 31302
83 + 31219 = 31302
109 + 31193 = 31302
113 + 31189 = 31302

Showing the first eight; more decompositions exist.
