Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499348, here are decompositions:

7 + 31499341 = 31499348
19 + 31499329 = 31499348
37 + 31499311 = 31499348
109 + 31499239 = 31499348
211 + 31499137 = 31499348
241 + 31499107 = 31499348
271 + 31499077 = 31499348
499 + 31498849 = 31499348

Showing the first eight; more decompositions exist.
