Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469242, here are decompositions:

3 + 31469239 = 31469242
173 + 31469069 = 31469242
419 + 31468823 = 31469242
449 + 31468793 = 31469242
653 + 31468589 = 31469242
683 + 31468559 = 31469242
719 + 31468523 = 31469242
743 + 31468499 = 31469242

Showing the first eight; more decompositions exist.
