Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620074, here are decompositions:

7 + 31620067 = 31620074
37 + 31620037 = 31620074
61 + 31620013 = 31620074
163 + 31619911 = 31620074
313 + 31619761 = 31620074
457 + 31619617 = 31620074
463 + 31619611 = 31620074
547 + 31619527 = 31620074

Showing the first eight; more decompositions exist.
