Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620962, here are decompositions:

19 + 31620943 = 31620962
31 + 31620931 = 31620962
199 + 31620763 = 31620962
211 + 31620751 = 31620962
229 + 31620733 = 31620962
283 + 31620679 = 31620962
463 + 31620499 = 31620962
619 + 31620343 = 31620962

Showing the first eight; more decompositions exist.
