Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525434, here are decompositions:

13 + 31525421 = 31525434
37 + 31525397 = 31525434
67 + 31525367 = 31525434
103 + 31525331 = 31525434
151 + 31525283 = 31525434
167 + 31525267 = 31525434
173 + 31525261 = 31525434
191 + 31525243 = 31525434

Showing the first eight; more decompositions exist.
