Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499364, here are decompositions:

23 + 31499341 = 31499364
37 + 31499327 = 31499364
41 + 31499323 = 31499364
53 + 31499311 = 31499364
67 + 31499297 = 31499364
73 + 31499291 = 31499364
97 + 31499267 = 31499364
137 + 31499227 = 31499364

Showing the first eight; more decompositions exist.
