Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625012, here are decompositions:

61 + 31624951 = 31625012
73 + 31624939 = 31625012
151 + 31624861 = 31625012
163 + 31624849 = 31625012
229 + 31624783 = 31625012
271 + 31624741 = 31625012
313 + 31624699 = 31625012
373 + 31624639 = 31625012

Showing the first eight; more decompositions exist.
