Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483262, here are decompositions:

193 + 31483069 = 31483262
211 + 31483051 = 31483262
271 + 31482991 = 31483262
373 + 31482889 = 31483262
439 + 31482823 = 31483262
463 + 31482799 = 31483262
619 + 31482643 = 31483262
631 + 31482631 = 31483262

Showing the first eight; more decompositions exist.
