Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483814, here are decompositions:

7 + 31483807 = 31483814
13 + 31483801 = 31483814
151 + 31483663 = 31483814
367 + 31483447 = 31483814
463 + 31483351 = 31483814
487 + 31483327 = 31483814
577 + 31483237 = 31483814
601 + 31483213 = 31483814

Showing the first eight; more decompositions exist.
