Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525362, here are decompositions:

19 + 31525343 = 31525362
31 + 31525331 = 31525362
73 + 31525289 = 31525362
79 + 31525283 = 31525362
83 + 31525279 = 31525362
101 + 31525261 = 31525362
149 + 31525213 = 31525362
151 + 31525211 = 31525362

Showing the first eight; more decompositions exist.
