Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474436, here are decompositions:

3 + 31474433 = 31474436
13 + 31474423 = 31474436
73 + 31474363 = 31474436
79 + 31474357 = 31474436
223 + 31474213 = 31474436
307 + 31474129 = 31474436
379 + 31474057 = 31474436
733 + 31473703 = 31474436

Showing the first eight; more decompositions exist.
