Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469650, here are decompositions:

29 + 31469621 = 31469650
71 + 31469579 = 31469650
89 + 31469561 = 31469650
131 + 31469519 = 31469650
137 + 31469513 = 31469650
227 + 31469423 = 31469650
239 + 31469411 = 31469650
263 + 31469387 = 31469650

Showing the first eight; more decompositions exist.
