Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469884, here are decompositions:

23 + 31469861 = 31469884
71 + 31469813 = 31469884
101 + 31469783 = 31469884
263 + 31469621 = 31469884
353 + 31469531 = 31469884
443 + 31469441 = 31469884
461 + 31469423 = 31469884
557 + 31469327 = 31469884

Showing the first eight; more decompositions exist.
