Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525542, here are decompositions:

5 + 31525537 = 31525542
43 + 31525499 = 31525542
53 + 31525489 = 31525542
163 + 31525379 = 31525542
199 + 31525343 = 31525542
211 + 31525331 = 31525542
263 + 31525279 = 31525542
281 + 31525261 = 31525542

Showing the first eight; more decompositions exist.
