Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483378, here are decompositions:

71 + 31483307 = 31483378
149 + 31483229 = 31483378
281 + 31483097 = 31483378
317 + 31483061 = 31483378
401 + 31482977 = 31483378
431 + 31482947 = 31483378
557 + 31482821 = 31483378
599 + 31482779 = 31483378

Showing the first eight; more decompositions exist.
