Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620070, here are decompositions:

3 + 31620067 = 31620070
11 + 31620059 = 31620070
89 + 31619981 = 31620070
227 + 31619843 = 31620070
263 + 31619807 = 31620070
269 + 31619801 = 31620070
281 + 31619789 = 31620070
311 + 31619759 = 31620070

Showing the first eight; more decompositions exist.
