Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525398, here are decompositions:

19 + 31525379 = 31525398
31 + 31525367 = 31525398
67 + 31525331 = 31525398
109 + 31525289 = 31525398
131 + 31525267 = 31525398
137 + 31525261 = 31525398
197 + 31525201 = 31525398
271 + 31525127 = 31525398

Showing the first eight; more decompositions exist.
