Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625346, here are decompositions:

43 + 31625303 = 31625346
83 + 31625263 = 31625346
167 + 31625179 = 31625346
197 + 31625149 = 31625346
199 + 31625147 = 31625346
307 + 31625039 = 31625346
367 + 31624979 = 31625346
419 + 31624927 = 31625346

Showing the first eight; more decompositions exist.
