Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625174, here are decompositions:

43 + 31625131 = 31625174
223 + 31624951 = 31625174
313 + 31624861 = 31625174
337 + 31624837 = 31625174
367 + 31624807 = 31625174
421 + 31624753 = 31625174
433 + 31624741 = 31625174
457 + 31624717 = 31625174

Showing the first eight; more decompositions exist.
