Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474556, here are decompositions:

7 + 31474549 = 31474556
37 + 31474519 = 31474556
67 + 31474489 = 31474556
193 + 31474363 = 31474556
199 + 31474357 = 31474556
307 + 31474249 = 31474556
499 + 31474057 = 31474556
523 + 31474033 = 31474556

Showing the first eight; more decompositions exist.
