Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483870, here are decompositions:

29 + 31483841 = 31483870
71 + 31483799 = 31483870
137 + 31483733 = 31483870
179 + 31483691 = 31483870
293 + 31483577 = 31483870
317 + 31483553 = 31483870
401 + 31483469 = 31483870
479 + 31483391 = 31483870

Showing the first eight; more decompositions exist.
