Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483906, here are decompositions:

17 + 31483889 = 31483906
23 + 31483883 = 31483906
29 + 31483877 = 31483906
107 + 31483799 = 31483906
173 + 31483733 = 31483906
257 + 31483649 = 31483906
353 + 31483553 = 31483906
359 + 31483547 = 31483906

Showing the first eight; more decompositions exist.
