Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469874, here are decompositions:

13 + 31469861 = 31469874
17 + 31469857 = 31469874
61 + 31469813 = 31469874
113 + 31469761 = 31469874
151 + 31469723 = 31469874
251 + 31469623 = 31469874
311 + 31469563 = 31469874
313 + 31469561 = 31469874

Showing the first eight; more decompositions exist.
