Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620694, here are decompositions:

11 + 31620683 = 31620694
113 + 31620581 = 31620694
173 + 31620521 = 31620694
197 + 31620497 = 31620694
251 + 31620443 = 31620694
263 + 31620431 = 31620694
431 + 31620263 = 31620694
491 + 31620203 = 31620694

Showing the first eight; more decompositions exist.
