Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469330, here are decompositions:

3 + 31469327 = 31469330
7 + 31469323 = 31469330
31 + 31469299 = 31469330
37 + 31469293 = 31469330
43 + 31469287 = 31469330
199 + 31469131 = 31469330
229 + 31469101 = 31469330
337 + 31468993 = 31469330

Showing the first eight; more decompositions exist.
