Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486424, here are decompositions:

7 + 31486417 = 31486424
31 + 31486393 = 31486424
37 + 31486387 = 31486424
97 + 31486327 = 31486424
157 + 31486267 = 31486424
223 + 31486201 = 31486424
337 + 31486087 = 31486424
601 + 31485823 = 31486424

Showing the first eight; more decompositions exist.
