Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474484, here are decompositions:

3 + 31474481 = 31474484
61 + 31474423 = 31474484
127 + 31474357 = 31474484
193 + 31474291 = 31474484
271 + 31474213 = 31474484
313 + 31474171 = 31474484
373 + 31474111 = 31474484
577 + 31473907 = 31474484

Showing the first eight; more decompositions exist.
