Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480662, here are decompositions:

13 + 31480649 = 31480662
23 + 31480639 = 31480662
41 + 31480621 = 31480662
229 + 31480433 = 31480662
271 + 31480391 = 31480662
281 + 31480381 = 31480662
293 + 31480369 = 31480662
313 + 31480349 = 31480662

Showing the first eight; more decompositions exist.
