Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499344, here are decompositions:

3 + 31499341 = 31499344
17 + 31499327 = 31499344
47 + 31499297 = 31499344
53 + 31499291 = 31499344
113 + 31499231 = 31499344
281 + 31499063 = 31499344
311 + 31499033 = 31499344
353 + 31498991 = 31499344

Showing the first eight; more decompositions exist.
