Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469722, here are decompositions:

101 + 31469621 = 31469722
191 + 31469531 = 31469722
281 + 31469441 = 31469722
311 + 31469411 = 31469722
419 + 31469303 = 31469722
443 + 31469279 = 31469722
653 + 31469069 = 31469722
821 + 31468901 = 31469722

Showing the first eight; more decompositions exist.
