Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483046, here are decompositions:

43 + 31483003 = 31483046
73 + 31482973 = 31483046
139 + 31482907 = 31483046
157 + 31482889 = 31483046
223 + 31482823 = 31483046
337 + 31482709 = 31483046
379 + 31482667 = 31483046
433 + 31482613 = 31483046

Showing the first eight; more decompositions exist.
