Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474444, here are decompositions:

11 + 31474433 = 31474444
41 + 31474403 = 31474444
47 + 31474397 = 31474444
101 + 31474343 = 31474444
137 + 31474307 = 31474444
191 + 31474253 = 31474444
227 + 31474217 = 31474444
383 + 31474061 = 31474444

Showing the first eight; more decompositions exist.
