Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469626, here are decompositions:

3 + 31469623 = 31469626
5 + 31469621 = 31469626
47 + 31469579 = 31469626
107 + 31469519 = 31469626
113 + 31469513 = 31469626
179 + 31469447 = 31469626
239 + 31469387 = 31469626
269 + 31469357 = 31469626

Showing the first eight; more decompositions exist.
