Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502934, here are decompositions:

7 + 31502927 = 31502934
11 + 31502923 = 31502934
37 + 31502897 = 31502934
53 + 31502881 = 31502934
157 + 31502777 = 31502934
173 + 31502761 = 31502934
191 + 31502743 = 31502934
233 + 31502701 = 31502934

Showing the first eight; more decompositions exist.
