Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620076, here are decompositions:

17 + 31620059 = 31620076
83 + 31619993 = 31620076
227 + 31619849 = 31620076
233 + 31619843 = 31620076
269 + 31619807 = 31620076
317 + 31619759 = 31620076
353 + 31619723 = 31620076
359 + 31619717 = 31620076

Showing the first eight; more decompositions exist.
