Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465370, here are decompositions:

7 + 31465363 = 31465370
61 + 31465309 = 31465370
127 + 31465243 = 31465370
193 + 31465177 = 31465370
241 + 31465129 = 31465370
271 + 31465099 = 31465370
331 + 31465039 = 31465370
337 + 31465033 = 31465370

Showing the first eight; more decompositions exist.
