Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620034, here are decompositions:

41 + 31619993 = 31620034
53 + 31619981 = 31620034
191 + 31619843 = 31620034
227 + 31619807 = 31620034
233 + 31619801 = 31620034
263 + 31619771 = 31620034
293 + 31619741 = 31620034
311 + 31619723 = 31620034

Showing the first eight; more decompositions exist.
