Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625954, here are decompositions:

37 + 31625917 = 31625954
43 + 31625911 = 31625954
181 + 31625773 = 31625954
193 + 31625761 = 31625954
223 + 31625731 = 31625954
307 + 31625647 = 31625954
337 + 31625617 = 31625954
487 + 31625467 = 31625954

Showing the first eight; more decompositions exist.
