Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469754, here are decompositions:

13 + 31469741 = 31469754
23 + 31469731 = 31469754
31 + 31469723 = 31469754
83 + 31469671 = 31469754
101 + 31469653 = 31469754
131 + 31469623 = 31469754
167 + 31469587 = 31469754
191 + 31469563 = 31469754

Showing the first eight; more decompositions exist.
