Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469854, here are decompositions:

5 + 31469849 = 31469854
41 + 31469813 = 31469854
71 + 31469783 = 31469854
113 + 31469741 = 31469854
131 + 31469723 = 31469854
233 + 31469621 = 31469854
293 + 31469561 = 31469854
431 + 31469423 = 31469854

Showing the first eight; more decompositions exist.
