Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620896, here are decompositions:

103 + 31620793 = 31620896
163 + 31620733 = 31620896
379 + 31620517 = 31620896
397 + 31620499 = 31620896
409 + 31620487 = 31620896
487 + 31620409 = 31620896
499 + 31620397 = 31620896
673 + 31620223 = 31620896

Showing the first eight; more decompositions exist.
