Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474446, here are decompositions:

13 + 31474433 = 31474446
23 + 31474423 = 31474446
43 + 31474403 = 31474446
83 + 31474363 = 31474446
89 + 31474357 = 31474446
103 + 31474343 = 31474446
127 + 31474319 = 31474446
139 + 31474307 = 31474446

Showing the first eight; more decompositions exist.
