Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474510, here are decompositions:

29 + 31474481 = 31474510
107 + 31474403 = 31474510
113 + 31474397 = 31474510
167 + 31474343 = 31474510
191 + 31474319 = 31474510
257 + 31474253 = 31474510
293 + 31474217 = 31474510
449 + 31474061 = 31474510

Showing the first eight; more decompositions exist.
