Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483846, here are decompositions:

5 + 31483841 = 31483846
47 + 31483799 = 31483846
113 + 31483733 = 31483846
197 + 31483649 = 31483846
263 + 31483583 = 31483846
269 + 31483577 = 31483846
293 + 31483553 = 31483846
353 + 31483493 = 31483846

Showing the first eight; more decompositions exist.
