Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473764, here are decompositions:

31 + 31473733 = 31473764
61 + 31473703 = 31473764
181 + 31473583 = 31473764
241 + 31473523 = 31473764
277 + 31473487 = 31473764
307 + 31473457 = 31473764
367 + 31473397 = 31473764
433 + 31473331 = 31473764

Showing the first eight; more decompositions exist.
