Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469836, here are decompositions:

23 + 31469813 = 31469836
53 + 31469783 = 31469836
113 + 31469723 = 31469836
257 + 31469579 = 31469836
317 + 31469519 = 31469836
389 + 31469447 = 31469836
449 + 31469387 = 31469836
479 + 31469357 = 31469836

Showing the first eight; more decompositions exist.
