Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625204, here are decompositions:

73 + 31625131 = 31625204
277 + 31624927 = 31625204
283 + 31624921 = 31625204
367 + 31624837 = 31625204
397 + 31624807 = 31625204
421 + 31624783 = 31625204
463 + 31624741 = 31625204
487 + 31624717 = 31625204

Showing the first eight; more decompositions exist.
