Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496248, here are decompositions:

29 + 31496219 = 31496248
107 + 31496141 = 31496248
149 + 31496099 = 31496248
191 + 31496057 = 31496248
269 + 31495979 = 31496248
389 + 31495859 = 31496248
401 + 31495847 = 31496248
491 + 31495757 = 31496248

Showing the first eight; more decompositions exist.
