Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469764, here are decompositions:

3 + 31469761 = 31469764
23 + 31469741 = 31469764
41 + 31469723 = 31469764
233 + 31469531 = 31469764
251 + 31469513 = 31469764
317 + 31469447 = 31469764
353 + 31469411 = 31469764
461 + 31469303 = 31469764

Showing the first eight; more decompositions exist.
