Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453376, here are decompositions:

43 + 31453333 = 31453376
109 + 31453267 = 31453376
127 + 31453249 = 31453376
337 + 31453039 = 31453376
433 + 31452943 = 31453376
547 + 31452829 = 31453376
607 + 31452769 = 31453376
613 + 31452763 = 31453376

Showing the first eight; more decompositions exist.
