Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625324, here are decompositions:

43 + 31625281 = 31625324
61 + 31625263 = 31625324
193 + 31625131 = 31625324
373 + 31624951 = 31625324
397 + 31624927 = 31625324
463 + 31624861 = 31625324
487 + 31624837 = 31625324
541 + 31624783 = 31625324

Showing the first eight; more decompositions exist.
