Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474600, here are decompositions:

23 + 31474577 = 31474600
29 + 31474571 = 31474600
41 + 31474559 = 31474600
167 + 31474433 = 31474600
197 + 31474403 = 31474600
257 + 31474343 = 31474600
281 + 31474319 = 31474600
293 + 31474307 = 31474600

Showing the first eight; more decompositions exist.
