Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469896, here are decompositions:

47 + 31469849 = 31469896
83 + 31469813 = 31469896
113 + 31469783 = 31469896
173 + 31469723 = 31469896
317 + 31469579 = 31469896
383 + 31469513 = 31469896
449 + 31469447 = 31469896
509 + 31469387 = 31469896

Showing the first eight; more decompositions exist.
