Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483958, here are decompositions:

31 + 31483927 = 31483958
97 + 31483861 = 31483958
139 + 31483819 = 31483958
151 + 31483807 = 31483958
157 + 31483801 = 31483958
199 + 31483759 = 31483958
409 + 31483549 = 31483958
487 + 31483471 = 31483958

Showing the first eight; more decompositions exist.
