Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469844, here are decompositions:

31 + 31469813 = 31469844
47 + 31469797 = 31469844
61 + 31469783 = 31469844
83 + 31469761 = 31469844
103 + 31469741 = 31469844
113 + 31469731 = 31469844
173 + 31469671 = 31469844
191 + 31469653 = 31469844

Showing the first eight; more decompositions exist.
