Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483406, here are decompositions:

37 + 31483369 = 31483406
79 + 31483327 = 31483406
193 + 31483213 = 31483406
313 + 31483093 = 31483406
337 + 31483069 = 31483406
433 + 31482973 = 31483406
499 + 31482907 = 31483406
547 + 31482859 = 31483406

Showing the first eight; more decompositions exist.
