Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486434, here are decompositions:

11 + 31486423 = 31486434
17 + 31486417 = 31486434
41 + 31486393 = 31486434
43 + 31486391 = 31486434
47 + 31486387 = 31486434
97 + 31486337 = 31486434
107 + 31486327 = 31486434
127 + 31486307 = 31486434

Showing the first eight; more decompositions exist.
