Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537214, here are decompositions:

13 + 31537201 = 31537214
61 + 31537153 = 31537214
67 + 31537147 = 31537214
127 + 31537087 = 31537214
211 + 31537003 = 31537214
223 + 31536991 = 31537214
271 + 31536943 = 31537214
277 + 31536937 = 31537214

Showing the first eight; more decompositions exist.
