Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486332, here are decompositions:

5 + 31486327 = 31486332
29 + 31486303 = 31486332
43 + 31486289 = 31486332
61 + 31486271 = 31486332
79 + 31486253 = 31486332
103 + 31486229 = 31486332
131 + 31486201 = 31486332
211 + 31486121 = 31486332

Showing the first eight; more decompositions exist.
