Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510350, here are decompositions:

29 + 31510321 = 31510350
31 + 31510319 = 31510350
41 + 31510309 = 31510350
107 + 31510243 = 31510350
127 + 31510223 = 31510350
163 + 31510187 = 31510350
181 + 31510169 = 31510350
211 + 31510139 = 31510350

Showing the first eight; more decompositions exist.
