Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625372, here are decompositions:

109 + 31625263 = 31625372
193 + 31625179 = 31625372
223 + 31625149 = 31625372
241 + 31625131 = 31625372
313 + 31625059 = 31625372
421 + 31624951 = 31625372
433 + 31624939 = 31625372
523 + 31624849 = 31625372

Showing the first eight; more decompositions exist.
