Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483442, here are decompositions:

13 + 31483429 = 31483442
73 + 31483369 = 31483442
181 + 31483261 = 31483442
229 + 31483213 = 31483442
349 + 31483093 = 31483442
373 + 31483069 = 31483442
439 + 31483003 = 31483442
619 + 31482823 = 31483442

Showing the first eight; more decompositions exist.
