Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525374, here are decompositions:

7 + 31525367 = 31525374
31 + 31525343 = 31525374
43 + 31525331 = 31525374
107 + 31525267 = 31525374
113 + 31525261 = 31525374
131 + 31525243 = 31525374
163 + 31525211 = 31525374
173 + 31525201 = 31525374

Showing the first eight; more decompositions exist.
