Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502460, here are decompositions:

19 + 31502441 = 31502460
29 + 31502431 = 31502460
89 + 31502371 = 31502460
97 + 31502363 = 31502460
107 + 31502353 = 31502460
127 + 31502333 = 31502460
131 + 31502329 = 31502460
149 + 31502311 = 31502460

Showing the first eight; more decompositions exist.
