Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625298, here are decompositions:

17 + 31625281 = 31625298
37 + 31625261 = 31625298
149 + 31625149 = 31625298
151 + 31625147 = 31625298
167 + 31625131 = 31625298
239 + 31625059 = 31625298
241 + 31625057 = 31625298
347 + 31624951 = 31625298

Showing the first eight; more decompositions exist.
