Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453776, here are decompositions:

43 + 31453733 = 31453776
97 + 31453679 = 31453776
199 + 31453577 = 31453776
269 + 31453507 = 31453776
293 + 31453483 = 31453776
313 + 31453463 = 31453776
349 + 31453427 = 31453776
383 + 31453393 = 31453776

Showing the first eight; more decompositions exist.
