Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453764, here are decompositions:

31 + 31453733 = 31453764
37 + 31453727 = 31453764
53 + 31453711 = 31453764
113 + 31453651 = 31453764
193 + 31453571 = 31453764
241 + 31453523 = 31453764
257 + 31453507 = 31453764
263 + 31453501 = 31453764

Showing the first eight; more decompositions exist.
