Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471416, here are decompositions:

5 + 31471411 = 31471416
19 + 31471397 = 31471416
29 + 31471387 = 31471416
43 + 31471373 = 31471416
59 + 31471357 = 31471416
127 + 31471289 = 31471416
199 + 31471217 = 31471416
269 + 31471147 = 31471416

Showing the first eight; more decompositions exist.
