Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502384, here are decompositions:

13 + 31502371 = 31502384
31 + 31502353 = 31502384
73 + 31502311 = 31502384
97 + 31502287 = 31502384
223 + 31502161 = 31502384
271 + 31502113 = 31502384
523 + 31501861 = 31502384
577 + 31501807 = 31502384

Showing the first eight; more decompositions exist.
