Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612070, here are decompositions:

73 + 31611997 = 31612070
163 + 31611907 = 31612070
229 + 31611841 = 31612070
241 + 31611829 = 31612070
313 + 31611757 = 31612070
337 + 31611733 = 31612070
367 + 31611703 = 31612070
397 + 31611673 = 31612070

Showing the first eight; more decompositions exist.
