Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480892, here are decompositions:

13 + 31480879 = 31480892
19 + 31480873 = 31480892
31 + 31480861 = 31480892
43 + 31480849 = 31480892
199 + 31480693 = 31480892
211 + 31480681 = 31480892
271 + 31480621 = 31480892
523 + 31480369 = 31480892

Showing the first eight; more decompositions exist.
