Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483148, here are decompositions:

31 + 31483117 = 31483148
61 + 31483087 = 31483148
79 + 31483069 = 31483148
97 + 31483051 = 31483148
157 + 31482991 = 31483148
241 + 31482907 = 31483148
349 + 31482799 = 31483148
439 + 31482709 = 31483148

Showing the first eight; more decompositions exist.
