Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31300, here are decompositions:

23 + 31277 = 31300
29 + 31271 = 31300
41 + 31259 = 31300
47 + 31253 = 31300
53 + 31247 = 31300
107 + 31193 = 31300
149 + 31151 = 31300
179 + 31121 = 31300

Showing the first eight; more decompositions exist.
