Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469572, here are decompositions:

3 + 31469569 = 31469572
11 + 31469561 = 31469572
41 + 31469531 = 31469572
53 + 31469519 = 31469572
59 + 31469513 = 31469572
131 + 31469441 = 31469572
149 + 31469423 = 31469572
269 + 31469303 = 31469572

Showing the first eight; more decompositions exist.
