Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469824, here are decompositions:

11 + 31469813 = 31469824
41 + 31469783 = 31469824
83 + 31469741 = 31469824
101 + 31469723 = 31469824
263 + 31469561 = 31469824
293 + 31469531 = 31469824
311 + 31469513 = 31469824
383 + 31469441 = 31469824

Showing the first eight; more decompositions exist.
