Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474588, here are decompositions:

11 + 31474577 = 31474588
17 + 31474571 = 31474588
29 + 31474559 = 31474588
107 + 31474481 = 31474588
191 + 31474397 = 31474588
269 + 31474319 = 31474588
281 + 31474307 = 31474588
617 + 31473971 = 31474588

Showing the first eight; more decompositions exist.
