Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496118, here are decompositions:

19 + 31496099 = 31496118
61 + 31496057 = 31496118
107 + 31496011 = 31496118
139 + 31495979 = 31496118
197 + 31495921 = 31496118
239 + 31495879 = 31496118
271 + 31495847 = 31496118
317 + 31495801 = 31496118

Showing the first eight; more decompositions exist.
