Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474406, here are decompositions:

3 + 31474403 = 31474406
43 + 31474363 = 31474406
157 + 31474249 = 31474406
193 + 31474213 = 31474406
277 + 31474129 = 31474406
349 + 31474057 = 31474406
373 + 31474033 = 31474406
499 + 31473907 = 31474406

Showing the first eight; more decompositions exist.
