Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469662, here are decompositions:

41 + 31469621 = 31469662
83 + 31469579 = 31469662
101 + 31469561 = 31469662
131 + 31469531 = 31469662
149 + 31469513 = 31469662
239 + 31469423 = 31469662
251 + 31469411 = 31469662
359 + 31469303 = 31469662

Showing the first eight; more decompositions exist.
