Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474694, here are decompositions:

3 + 31474691 = 31474694
7 + 31474687 = 31474694
193 + 31474501 = 31474694
271 + 31474423 = 31474694
331 + 31474363 = 31474694
337 + 31474357 = 31474694
523 + 31474171 = 31474694
661 + 31474033 = 31474694

Showing the first eight; more decompositions exist.
