Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474366, here are decompositions:

3 + 31474363 = 31474366
23 + 31474343 = 31474366
47 + 31474319 = 31474366
59 + 31474307 = 31474366
113 + 31474253 = 31474366
149 + 31474217 = 31474366
293 + 31474073 = 31474366
359 + 31474007 = 31474366

Showing the first eight; more decompositions exist.
