Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469952, here are decompositions:

29 + 31469923 = 31469952
103 + 31469849 = 31469952
139 + 31469813 = 31469952
191 + 31469761 = 31469952
211 + 31469741 = 31469952
229 + 31469723 = 31469952
263 + 31469689 = 31469952
281 + 31469671 = 31469952

Showing the first eight; more decompositions exist.
