Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469866, here are decompositions:

5 + 31469861 = 31469866
17 + 31469849 = 31469866
53 + 31469813 = 31469866
83 + 31469783 = 31469866
347 + 31469519 = 31469866
353 + 31469513 = 31469866
419 + 31469447 = 31469866
443 + 31469423 = 31469866

Showing the first eight; more decompositions exist.
