Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502484, here are decompositions:

43 + 31502441 = 31502484
53 + 31502431 = 31502484
113 + 31502371 = 31502484
131 + 31502353 = 31502484
151 + 31502333 = 31502484
173 + 31502311 = 31502484
197 + 31502287 = 31502484
241 + 31502243 = 31502484

Showing the first eight; more decompositions exist.
