Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486374, here are decompositions:

37 + 31486337 = 31486374
47 + 31486327 = 31486374
67 + 31486307 = 31486374
71 + 31486303 = 31486374
103 + 31486271 = 31486374
107 + 31486267 = 31486374
173 + 31486201 = 31486374
211 + 31486163 = 31486374

Showing the first eight; more decompositions exist.
