Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474474, here are decompositions:

41 + 31474433 = 31474474
71 + 31474403 = 31474474
131 + 31474343 = 31474474
167 + 31474307 = 31474474
173 + 31474301 = 31474474
257 + 31474217 = 31474474
401 + 31474073 = 31474474
431 + 31474043 = 31474474

Showing the first eight; more decompositions exist.
