Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474416, here are decompositions:

13 + 31474403 = 31474416
19 + 31474397 = 31474416
53 + 31474363 = 31474416
59 + 31474357 = 31474416
73 + 31474343 = 31474416
97 + 31474319 = 31474416
109 + 31474307 = 31474416
163 + 31474253 = 31474416

Showing the first eight; more decompositions exist.
