Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469272, here are decompositions:

239 + 31469033 = 31469272
353 + 31468919 = 31469272
449 + 31468823 = 31469272
479 + 31468793 = 31469272
641 + 31468631 = 31469272
683 + 31468589 = 31469272
701 + 31468571 = 31469272
719 + 31468553 = 31469272

Showing the first eight; more decompositions exist.
