Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469184, here are decompositions:

7 + 31469177 = 31469184
41 + 31469143 = 31469184
53 + 31469131 = 31469184
83 + 31469101 = 31469184
151 + 31469033 = 31469184
157 + 31469027 = 31469184
191 + 31468993 = 31469184
281 + 31468903 = 31469184

Showing the first eight; more decompositions exist.
