Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483838, here are decompositions:

19 + 31483819 = 31483838
31 + 31483807 = 31483838
37 + 31483801 = 31483838
79 + 31483759 = 31483838
241 + 31483597 = 31483838
367 + 31483471 = 31483838
409 + 31483429 = 31483838
487 + 31483351 = 31483838

Showing the first eight; more decompositions exist.
