Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525314, here are decompositions:

31 + 31525283 = 31525314
47 + 31525267 = 31525314
53 + 31525261 = 31525314
71 + 31525243 = 31525314
101 + 31525213 = 31525314
103 + 31525211 = 31525314
113 + 31525201 = 31525314
131 + 31525183 = 31525314

Showing the first eight; more decompositions exist.
