Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486362, here are decompositions:

13 + 31486349 = 31486362
23 + 31486339 = 31486362
59 + 31486303 = 31486362
73 + 31486289 = 31486362
79 + 31486283 = 31486362
109 + 31486253 = 31486362
199 + 31486163 = 31486362
233 + 31486129 = 31486362

Showing the first eight; more decompositions exist.
