Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625274, here are decompositions:

11 + 31625263 = 31625274
13 + 31625261 = 31625274
127 + 31625147 = 31625274
347 + 31624927 = 31625274
353 + 31624921 = 31625274
367 + 31624907 = 31625274
467 + 31624807 = 31625274
491 + 31624783 = 31625274

Showing the first eight; more decompositions exist.
