Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620044, here are decompositions:

7 + 31620037 = 31620044
31 + 31620013 = 31620044
223 + 31619821 = 31620044
283 + 31619761 = 31620044
331 + 31619713 = 31620044
397 + 31619647 = 31620044
433 + 31619611 = 31620044
487 + 31619557 = 31620044

Showing the first eight; more decompositions exist.
