Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474384, here are decompositions:

41 + 31474343 = 31474384
83 + 31474301 = 31474384
131 + 31474253 = 31474384
167 + 31474217 = 31474384
311 + 31474073 = 31474384
467 + 31473917 = 31474384
521 + 31473863 = 31474384
677 + 31473707 = 31474384

Showing the first eight; more decompositions exist.
