Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620794, here are decompositions:

31 + 31620763 = 31620794
43 + 31620751 = 31620794
61 + 31620733 = 31620794
193 + 31620601 = 31620794
223 + 31620571 = 31620794
277 + 31620517 = 31620794
307 + 31620487 = 31620794
313 + 31620481 = 31620794

Showing the first eight; more decompositions exist.
