Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625246, here are decompositions:

67 + 31625179 = 31625246
97 + 31625149 = 31625246
307 + 31624939 = 31625246
397 + 31624849 = 31625246
409 + 31624837 = 31625246
439 + 31624807 = 31625246
463 + 31624783 = 31625246
547 + 31624699 = 31625246

Showing the first eight; more decompositions exist.
