Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480692, here are decompositions:

11 + 31480681 = 31480692
43 + 31480649 = 31480692
53 + 31480639 = 31480692
71 + 31480621 = 31480692
163 + 31480529 = 31480692
251 + 31480441 = 31480692
311 + 31480381 = 31480692
433 + 31480259 = 31480692

Showing the first eight; more decompositions exist.
