Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502326, here are decompositions:

47 + 31502279 = 31502326
83 + 31502243 = 31502326
113 + 31502213 = 31502326
137 + 31502189 = 31502326
179 + 31502147 = 31502326
197 + 31502129 = 31502326
227 + 31502099 = 31502326
347 + 31501979 = 31502326

Showing the first eight; more decompositions exist.
