Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469032, here are decompositions:

5 + 31469027 = 31469032
113 + 31468919 = 31469032
131 + 31468901 = 31469032
239 + 31468793 = 31469032
401 + 31468631 = 31469032
443 + 31468589 = 31469032
461 + 31468571 = 31469032
479 + 31468553 = 31469032

Showing the first eight; more decompositions exist.
