Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483884, here are decompositions:

7 + 31483877 = 31483884
13 + 31483871 = 31483884
23 + 31483861 = 31483884
43 + 31483841 = 31483884
83 + 31483801 = 31483884
151 + 31483733 = 31483884
193 + 31483691 = 31483884
307 + 31483577 = 31483884

Showing the first eight; more decompositions exist.
