Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625262, here are decompositions:

83 + 31625179 = 31625262
113 + 31625149 = 31625262
131 + 31625131 = 31625262
223 + 31625039 = 31625262
283 + 31624979 = 31625262
311 + 31624951 = 31625262
401 + 31624861 = 31625262
433 + 31624829 = 31625262

Showing the first eight; more decompositions exist.
