Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469620, here are decompositions:

41 + 31469579 = 31469620
59 + 31469561 = 31469620
89 + 31469531 = 31469620
101 + 31469519 = 31469620
107 + 31469513 = 31469620
173 + 31469447 = 31469620
179 + 31469441 = 31469620
197 + 31469423 = 31469620

Showing the first eight; more decompositions exist.
